An Overview of Social Exclusion

Introduction

Social exclusion or social marginalisation is the social disadvantage and relegation to the fringe of society. It is a term that has been used widely in Europe and was first used in France in the late 20th century. In the EU context, the European Commission defines it as “a situation whereby a person is prevented (or excluded) from contributing to and benefiting from economic and social progress”. It is used across disciplines including education, sociology, psychology, healthcare, politics and economics.

Social exclusion is the process in which individuals are blocked from (or denied full access to) various rights, opportunities and resources that are normally available to members of a different group, and which are fundamental to social integration and observance of human rights within that particular group] (e.g. due process).

Alienation or disenfranchisement resulting from social exclusion can be connected to a person’s social class, race, skin colour, religious affiliation, ethnic origin, caste, educational status, childhood relationships, living standards, and or political opinions, and appearance. Such exclusionary forms of discrimination may also apply to disabled people, minorities, LGBTQ+ people, drug users, institutional care leavers, the elderly and the young. Anyone who appears to deviate in any way from perceived norms of a population may thereby become subject to coarse or subtle forms of social exclusion.

The outcome of social exclusion is that affected individuals or communities are prevented from participating fully in the economic, social, and political life of the society in which they live. This may result in resistance in the form of demonstrations, protests or lobbying from the excluded people.

The concept of social exclusion has led to the researcher’s conclusion that in many European countries the impact of social disadvantages, that influence the well-being of all people, including with special needs, has an increasingly negative impact.

Most of the characteristics listed in this article are present together in studies of social exclusion, due to exclusion’s multidimensionality.

Another way of articulating the definition of social exclusion is as follows:

Social exclusion is a multidimensional process of progressive social rupture, detaching groups and individuals from social relations and institutions and preventing them from full participation in the normal, normatively prescribed activities of the society in which they live.

In an alternative conceptualization, social exclusion theoretically emerges at the individual or group level on four correlated dimensions:

  1. Insufficient access to social rights;
  2. Material deprivation;
  3. Limited social participation; and
  4. A lack of normative integration.

It is then regarded as the combined result of:

  • Personal risk factors (age, gender, race);
  • Macro-societal changes (demographic, economic and labour market developments, technological innovation, the evolution of social norms);
  • Government legislation and social policy; and
  • The actual behaviour of businesses, administrative organisations and fellow citizens.

Individual Exclusion

“The marginal man…is one whom fate has condemned to live in two societies and in two, not merely different but antagonistic cultures….his mind is the crucible in which two different and refractory cultures may be said to melt and, either wholly or in part, fuse.”

Social exclusion at the individual level results in an individual’s exclusion from meaningful participation in society. An example is the exclusion of single mothers from the welfare system prior to welfare reforms of the 1900s. The modern welfare system is based on the concept of entitlement to the basic means of being a productive member of society both as an organic function of society and as compensation for the socially useful labour provided. A single mother’s contribution to society is not based on formal employment, but on the notion that provision of welfare for children is a necessary social expense. In some career contexts, caring work is devalued and motherhood is seen as a barrier to employment. Single mothers were previously marginalised in spite of their significant role in the socializing of children due to views that an individual can only contribute meaningfully to society through “gainful” employment as well as a cultural bias against unwed mothers. When the father’s sole task was seen as the breadwinner, his marginalisation was primarily a function of class condition. Solo fatherhood brings additional trials due to society being less accepting of males ‘getting away with’ not working and the general invisibility/lack of acknowledgment of single fathers in society. Acknowledgment of the needs participatory fathers may have can be found by examining the changes from the original clinical report on the father’s role published by the American Academy of Paediatrics in May 2004. Eight week paternity leave is a good example of one social change. Child health care providers have an opportunity to have a greater influence on the child and family structure by supporting fathers and enhancing a father’s involvement.

More broadly, many women face social exclusion. Moosa-Mitha discusses the Western feminist movement as a direct reaction to the marginalisation of white women in society. Women were excluded from the labour force and their work in the home was not valued. Feminists argued that men and women should equally participate in the labour force, in the public and private sector, and in the home. They also focused on labour laws to increase access to employment as well as to recognise child-rearing as a valuable form of labour. In some places today, women are still marginalised from executive positions and continue to earn less than men in upper management positions.

Another example of individual marginalisation is the exclusion of individuals with disabilities from the labour force. Grandz discusses an employer’s viewpoint about hiring individuals living with disabilities as jeopardising productivity, increasing the rate of absenteeism, and creating more accidents in the workplace. Cantor also discusses employer concern about the excessively high cost of accommodating people with disabilities. The marginalisation of individuals with disabilities is prevalent today, despite the legislation intended to prevent it in most western countries, and the academic achievements, skills and training of many disabled people.

There are also exclusions of sexual minorities because of their sexual orientation, gender identity, and/or sexual characteristics. The Yogyakarta Principles require that the states and communities abolish any stereotypes about LGBT people as well as stereotyped gender roles.

“Isolation is common to almost every vocational, religious or cultural group of a large city. Each develops its own sentiments, attitudes, codes, even its own words, which are at best only partially intelligible to others.”

Community Exclusion

Many communities experience social exclusion, such as racial (e.g. black), caste (e.g. untouchables or dalits in some regions in India), and economic (e.g. Romani) communities.

One example is the Aboriginal community in Australia. The marginalisation of Aboriginal communities is a product of colonisation. As a result of colonialism, Aboriginal communities lost their land, were forced into destitute areas, lost their sources of livelihood, were excluded from the labour market and were subjected to widespread unpunished massacres. Additionally, Aboriginal communities lost their culture and values through forced assimilation and lost their rights in society. Today, various Aboriginal communities continue to be marginalised from society due to the development of practices, policies and programs that, according to J. Yee, “met the needs of white people and not the needs of the marginalized groups themselves”. Yee also connects marginalisation to minority communities, when describing the concept of whiteness as maintaining and enforcing dominant norms and discourse. Poor people living in run-down council estates and areas with high crime can be locked into social deprivation

Contributors

Social exclusion has many contributors. Major contributors include race, income, employment status, social class, geographic location; personal habits, appearance, or interests (i.e. a favourite hobby, sports team, or music genre); education, religion, and political affiliation.

Global and Structural

Globalisation (global capitalism), immigration, social welfare, and policy are broader social structures that have the potential to contribute negatively to one’s access to resources and services, resulting in the social exclusion of individuals and groups. Similarly, increasing use of information technology and the company outsourcing have contributed to job insecurity and a widening gap between the rich and the poor. Flobalisation sets forth a decrease in the role of the state with an increase in support from various “corporate sectors resulting in gross inequalities, injustices and marginalization of various vulnerable groups”. Companies are outsourcing, jobs are lost, the cost of living continues to rise, and the land is being expropriated by large companies. Material goods are made in large abundances and sold at cheaper costs, while in India for example, the poverty line is lowered in order to mask the number of individuals who are actually living in poverty as a result of globalization. Globalization and structural forces aggravate poverty and continue to push individuals to the margins of society, while governments and large corporations do not address the issues (George, P, SK8101, lecture, 09 October 2007).

Certain language and the meaning attached to language can cause universalising discourses that are influenced by the Western world, which is what Sewpaul (2006) describes as the “potential to dilute or even annihilate local cultures and traditions and to deny context-specific realities” (p. 421). What Sewpaul (2006) is implying is that the effect of dominant global discourses can cause individual and cultural displacement, as well as sex safety are jeopardised (p. 422). Insecurity and fear of an unknown future and instability can result in displacement, exclusion, and forced assimilation into the dominant group. For many, it further pushes them to the margins of society or enlists new members to the outskirts because of global-capitalism and dominant discourses (Sewpaul, 2006).

With the prevailing notion of globalisation, we now see the rise of immigration as the world gets smaller and smaller with millions of individuals relocating each year. This is not without hardship and struggle of what a newcomer thought was going to be a new life with new opportunities. Immigration has had a strong link to the access of welfare support programmes. Newcomers are constantly bombarded with the inability to access a country’s resources because they are seen as “undeserving foreigners” (p. 132). With this comes a denial of access to public housing, health care benefits, employment support services, and social security benefits. Newcomers are seen as undeserving, or that they must prove their entitlement in order to gain access to basic support necessities. It is clear that individuals are exploited and marginalised within the country they have emigrated.

Welfare states and social policies can also exclude individuals from basic necessities and support programmes. Welfare payments were proposed to assist individuals in accessing a small amount of material wealth (Young, 2000). Young (2000) further discusses how “the provision of the welfare itself produces new injustice by depriving those dependent on it of rights and freedoms that others have…marginalization is unjust because it blocks the opportunity to exercise capacities in socially defined and recognized way” (p. 41). There is the notion that by providing a minimal amount of welfare support, an individual will be free from marginalisation. In fact, welfare support programmes further lead to injustices by restricting certain behaviour, as well the individual is mandated to other agencies. The individual is forced into a new system of rules while facing social stigma and stereotypes from the dominant group in society, further marginalising and excluding individuals (Young, 2000). Thus, social policy and welfare provisions reflect the dominant notions in society by constructing and reinforcing categories of people and their needs. It ignores the unique-subjective human essence, further continuing the cycle of dominance.

Unemployment

Whilst recognising the multi-dimensionality of exclusion, policy work undertaken in the EU focused on unemployment as a key cause of, or at least correlating with, social exclusion. This is because, in modern societies, paid work is not only the principal source of income with which to buy services but is also the fount of individuals’ identity and feeling of self-worth. Most people’s social networks and a sense of embeddedness in society also revolve around their work. Many of the indicators of extreme social exclusion, such as poverty and homelessness, depend on monetary income which is normally derived from work. Social exclusion can be a possible result of long-term unemployment, especially in countries with weak welfare safety nets. Much policy to reduce exclusion thus focuses on the labour market:

  • On the one hand, to make individuals at risk of exclusion more attractive to employers, i.e. more “employable”.
  • On the other hand, to encourage (and/or oblige) employers to be more inclusive in their employment policies.

The EU’s EQUAL Community Initiative investigated ways to increase the inclusiveness of the labour market. Work on social exclusion more broadly is carried out through the Open Method of Coordination (OMC) among the Member State governments. The United Nations Sustainable Development Goal 10 is also an example of global initiatives aimed at promoting social inclusion for all by 2030.

Religion

Some religious traditions recommend excommunication of individuals said to deviate from religious teaching, and in some instances shunning by family members. Some religious organisations permit the censure of critics.

Across societies, individuals and communities can be socially excluded on the basis of their religious beliefs. Social hostility against religious minorities and communal violence occur in areas where governments do not have policies restricting the religious practise of minorities. A study by the Pew Research Centre on international religious freedom found that 61% of countries have social hostilities that tend to target religious minorities. The five highest social hostility scores were for Pakistan, India, Sri Lanka, Iraq, and Bangladesh. In 2015, Pew published that social hostilities declined in 2013, but harassment of Jews increased.

Sport

Parts of 2024 Summer Olympics opening ceremony have been criticised by some as divisive due to singling out one particular religion (Christianity).

Consequences

Health

In gay men, results of psycho-emotional damage from marginalisation from a heteronormative society include suicide and drug addiction.

Scientists have been studying the impact of racism on health. Amani Nuru-Jeter, a social epidemiologist at the University of California, Berkeley and other doctors have been hypothesizing that exposure to chronic stress may be one way racism contributes to health disparities between racial groups. Arline Geronimus, a research professor at the University of Michigan Institute for Social Research and a professor at the School of Public Health, and her colleagues found that psychosocial stress associated with living in extreme poverty can cause early onset of age-related diseases. The 2015 study titled, “Race-Ethnicity, Poverty, Urban Stressors, and Telomere Length in a Detroit Community-based Sample” was conducted in order to determine the impact of living conditions on health and was performed by a multi-university team of social scientists, cellular biologists and community partners, including the Healthy Environments Partnership (HEP) to measure the telomere length of poor and moderate-income people of White, African-American and Mexican race.

In 2006, there was research focused on possible connections between exclusion and brain function. Studies published by both the University of Georgia and San Diego State University found that exclusion can lead to diminished brain functioning and poor decision making. Such studies corroborate with earlier beliefs of sociologists. The effect of social exclusion have been hypothesized in various past research studies to correlate with such things as substance abuse and addiction, and crime.

Economics

The problem of social exclusion is usually tied to that of equal opportunity, as some people are more subject to such exclusion than others. Marginalisation of certain groups is a problem in many economically more developed countries where the majority of the population enjoys considerable economic and social opportunities.

In Philosophy

The marginal, the processes of marginalisation, etc. bring specific interest in postmodern and post-colonial philosophy and social studies. Postmodernism question the “centre” about its authenticity and postmodern sociology and cultural studies research marginal cultures, behaviours, societies, the situation of the marginalised individual, etc.

Social Inclusion

Social inclusion is the converse of social exclusion. As the World Bank states, social inclusion is the process of improving the ability, opportunity, and worthiness of people, disadvantaged on the basis of their identity, to take part in society. The World Bank’s 2019 World Development Report on The Changing Nature of Work suggests that enhanced social protection and better investments in human capital improve equality of opportunity and social inclusion. Social inclusion can be measured individually.

Social Inclusion ministers have been appointed, and special units established, in a number of jurisdictions around the world. The first Minister for Social Inclusion was Premier of South Australia Mike Rann, who took the portfolio in 2004. Based on the UK’s Social Exclusion Unit, established by Prime Minister Tony Blair in 1997, Rann established the Social Inclusion Initiative in 2002. It was headed by Monsignor David Cappo and was serviced by a unit within the department of Premier and Cabinet. Cappo sat on the executive committee of the South Australian Cabinet and was later appointed Social Inclusion Commissioner with wide powers to address social disadvantage. Cappo was allowed to roam across agencies given that most social disadvantage has multiple causes necessitating a “joined up” rather than a single agency response.[48] The Initiative drove a big investment by the South Australian Government in strategies to combat homelessness, including establishing Common Ground, building high quality inner city apartments for “rough sleeping” homeless people, the Street to Home initiative and the ICAN flexible learning program designed to improve school retention rates. It also included major funding to revamp mental health services following Cappo’s “Stepping Up” report, which focused on the need for community and intermediate levels of care and an overhaul of disability services. In 2007, the then Australian Prime Minister Kevin Rudd appointed Julia Gillard as the nation’s first Social Inclusion Minister.

In Japan, the concept and term “social inclusion” went through a number of changes over time and eventually became incorporated in community-based activities under the names hōsetsu (包摂) and hōkatsu (包括), such as in the “Community General Support Centres” (chiiki hōkatsu shien sentā 地域包括支援センター) and “Community-based Integrated Care System” (chiiki hōkatsu kea shisutemu 地域包括ケアシステム).[53]

One may explore its implications for social work practice. Mullaly (2007) describes how “the personal is political” and the need for recognising that social problems are indeed connected with larger structures in society, causing various forms of oppression amongst individuals resulting in marginalisation. It is also important for the social worker to recognise the intersecting nature of oppression. A non-judgmental and unbiased attitude is necessary on the part of the social worker. The worker may begin to understand oppression and marginalisation as a systemic problem, not the fault of the individual.

Working under an anti-oppression perspective would then allow the social worker to understand the lived, subjective experiences of the individual, as well as their cultural, historical and social background. The worker should recognize the individual as political in the process of becoming a valuable member of society and the structural factors that contribute to oppression and marginalisation (Mullaly, 2007). Social workers must take a firm stance on naming and labelling global forces that impact individuals and communities who are then left with no support, leading to marginalisation or further marginalisation from the society they once knew (George, P, SK8101, lecture, 09 October 2007).

The social worker should be constantly reflexive, work to raise the consciousness, empower, and understand the lived subjective realities of individuals living in a fast-paced world, where fear and insecurity constantly subjugate the individual from the collective whole, perpetuating the dominant forces, while silencing the oppressed.

Some individuals and groups who are not professional social workers build relationships with marginalised persons by providing relational care and support, for example, through homeless ministry. These relationships validate the individuals who are marginalised and provide them a meaningful contact with the mainstream.

In Law

There are countries, Italy for example, that have a legal concept of social exclusion. In Italy, “esclusione sociale” is defined as poverty combined with social alienation, by the statute n. 328 (11-8-2000), that instituted a state investigation commission named “Commissione di indagine sull’Esclusione Sociale” (CIES) to make an annual report to the government on legally expected issues of social exclusion.

The Vienna Declaration and Programme of Action, a document on international human rights instruments affirms that:

“extreme poverty and social exclusion constitute a violation of human dignity and that urgent steps are necessary to achieve better knowledge of extreme poverty and its causes, including those related to the program of development, in order to promote the human rights of the poorest, and to put an end to extreme poverty and social exclusion and promote the enjoyment of the fruits of social progress. It is essential for States to foster participation by the poorest people in the decision making process by the community in which they live, the promotion of human rights and efforts to combat extreme poverty.”

What is Social Isolation?

Introduction

Social isolation is a state of complete or near-complete lack of contact between an individual and society. It differs from loneliness, which reflects temporary and involuntary lack of contact with other humans in the world. Social isolation can be an issue for individuals of any age, though symptoms may differ by age group.

Social isolation has similar characteristics in both temporary instances and for those with a historical lifelong isolation cycle. All types of social isolation can include staying home for lengthy periods of time, having no communication with family, acquaintances or friends, and/or wilfully avoiding any contact with other humans when those opportunities do arise.

Effects

True social isolation over years and decades can be a chronic condition affecting all aspects of a person’s existence. Social isolation can lead to feelings of loneliness, fear of others, or negative self-esteem. Lack of consistent human contact can also cause conflict with (peripheral) friends. The socially isolated person may occasionally talk to or cause problems with family members.

In the case of mood-related isolation, the individual may isolate during a depressive episode only to ‘surface’ when their mood improves. The individual may attempt to justify their reclusive or isolating behaviour as enjoyable or comfortable. There can be an inner realisation on the part of the individual that there is something wrong with their isolating responses which can lead to heightened anxiety. Relationships can be a struggle, as the individual may reconnect with others during a healthier mood only to return to an isolated state during a subsequent low or depressed mood.

Perceived Social Isolation in Humans

Research indicates that perceived social isolation (PSI) is a risk factor for and may contribute to “poorer overall cognitive performance and poorer executive functioning, faster cognitive decline, more negative and depressive cognition, heightened sensitivity to social threats, and a self-protective confirmatory bias in social cognition.” PSI also contributes to accelerating the ageing process: Wilson et al. (2007) reported that, after controlling for social network size and frequency of social activity, perceived social isolation is predictive of cognitive decline and risk for Alzheimer’s disease. Moreover, the social interactions of individuals who feel socially isolated are more negative and less subjectively satisfying. This contributes to a vicious cycle in which the person becomes more and more isolated.

Neuroimaging Studies

In the first resting state fMRI functional connectivity (FC) study on PSI, PSI was found to be associated with increased resting-state FC between several nodes of the cingulo-opercular network, a neural network associated with tonic alertness. PSI was also associated with reduced resting-state FC between the cingulo-opercular network and the right superior frontal gyrus, suggesting diminished executive control. Cacioppo and colleagues (2009) found that lonely individuals express weaker activation of the ventral striatum in response to pleasant pictures of people than of objects, suggesting decreased reward to social stimuli. Lonely individuals also expressed greater activation of the visual cortex in response to unpleasant depictions of people (i.e. negative facial expressions) than of objects; non-lonely individuals show greater activation of the right and left temporoparietal junction (TPJ), a region implicated in theory of mind. The authors interpreted the findings to represent that lonely individuals pay greater attention to negative social stimuli, but non-lonely individuals, to a greater degree than lonely individuals, insert themselves into the perspective of others. Moreover, Kanai et al. (2012) reported that loneliness negatively correlated with gray matter density in the left posterior temporal sulcus, an area involved in biological motion perception, mentalising, and social perception.

Overall, several neuroimaging studies in humans on perceived social isolation have emphasized implications of the visual cortex and right-hemispheric stress-related circuits underlying difference between lonely and non-lonely individuals. One population-genetics study marked a 50× increase in the neuroimaging research on perceived social isolation. The investigators tested for signatures of loneliness in grey matter morphology, intrinsic functional coupling, and fibre tract microstructure. The loneliness-linked neurobiological profiles converged on a collection of brain regions known as the default mode network. This higher associative network shows more consistent loneliness associations in grey matter volume than other cortical brain networks. Lonely individuals display stronger functional communication in the default network, and greater microstructural integrity of its fornix pathway. The findings fit with the possibility that the up-regulation of these neural circuits supports mentalising, reminiscence and imagination to fill the social void.

Social Isolation in Rodents

Experimental manipulations of social isolation in rats and mice (e.g. isolated rearing) are a common means of elucidating the effects of isolation on social animals in general. Researchers have proposed isolated rearing of rats as an etiologically valid model of human mental illness. Indeed, chronic social isolation in rats has been found to lead to depression-, anxiety-, and psychosis-like behaviours as well signs of autonomic, neuroendocrine, and metabolic dysregulation. For example, a systematic review found that social isolation in rats is associated with increased expression of BDNF in the hippocampus, which is associated with increased anxiety-like symptoms. In another example, a study found that social isolation in rats is associated with increased brain-derived neurotrophic factor (BDNF) expression in the prefrontal cortex. This results in the dysregulation of neural activity which is associated with anxiety, depression, and social dysfunction.

The effects of experimental manipulations of isolation in nonhuman social species has been shown to resemble the effects of perceived isolation in humans, and include: increased tonic sympathetic tone and hypothalamic-pituitary-adrenal (HPA) activation and decreased inflammatory control, immunity, sleep salubrity, and expression of genes regulating glucocorticoid responses. However, the biological, neurological, and genetic mechanisms underlying these symptoms are poorly understood.

Neurobiology

Social isolation contributes to abnormal hippocampal development via specific alterations to microtubule stability and decreased MAP-2 expression. Social isolation contributes to decreased expression of the synaptic protein synaptophysin and decreased dendritic length and dendritic spine density of pyramidal cells. The underlying molecular mechanism of these structural neuronal alterations are microtubule stabilisations, which impair the remodelling and extension of axons and dendrites.

Research by Cole and colleagues showed that perceived social isolation is associated with gene expression – specifically, the under-expression of genes bearing anti-inflammatory glucocorticoid response elements and over-expression of genes bearing response elements for pro-inflammatory NF-κB/Rel transcription factors. This finding is paralleled by decreased lymphocyte sensitivity to physiological regulation by the HPA axis in lonely individuals. This, together with evidence of increased activity of the HPA axis, suggests the development of glucocorticoid resistance in chronically lonely individuals.

Social isolation can be a precipitating factor for suicidal behaviour. A large body of literature suggests that individuals who experience isolation in their lives are more vulnerable to suicide than those who have strong social ties with others. A study found social isolation to be among the most common risk factors identified by Australian men who attempt suicide. Professor Ian Hickie of the University of Sydney said that social isolation was perhaps the most important factor contributing to male suicide attempts. Hickie said there was a wealth of evidence that men had more restricted social networks than women, and that these networks were heavily work-based.

A lack of social relationships negatively impacts the development of the brain’s structure. In extreme cases of social isolation, studies of young mice and monkeys have shown how the brain is strongly affected by a lack of social behaviour and relationships.

In Social Animal Species in General

In a hypothesis proposed by Cacioppo and colleagues, the isolation of a member of a social species has detrimental biological effects. In a 2009 review, Cacioppo and Hawkley noted that the health, life, and genetic legacy of members of social species are threatened when they find themselves on the social perimeter. For instance, social isolation decreases lifespan in the fruit fly; promotes obesity and type 2 diabetes in mice; exacerbates infarct size and oedema and decreases post-stroke survival rate following experimentally induced stroke in mice; promotes activation of the sympatho-adrenomedullary response to an acute immobilisation or cold stressor in rats; delays the effects of exercise on adult neurogenesis in rats; decreases open field activity, increases basal cortisol concentrations, and decreases lymphocyte proliferation to mitogens in pigs; increases the 24-hour urinary catecholamine levels and evidence of oxidative stress in the aortic arch of rabbits; and decreases the expression of genes regulating glucocorticoid response in the frontal cortex.

Social isolation in the common starling, a highly social, flocking species of bird, has also been shown to stress the isolated birds.

Background

Social isolation is both a potential cause and a symptom of emotional or psychological challenges. As a cause, the perceived inability to interact with the world and others can create an escalating pattern of these challenges. As a symptom, periods of isolation can be chronic or episodic, depending upon any cyclical changes in mood, especially in the case of clinical depression.

Every day aspects of this type of deep-rooted social isolation can mean:

  • Staying home for an indefinite period of time due to lack of access to social situations rather than a desire to be alone;
  • Both not contacting, and not being contacted by, any acquaintances, even peripherally; for example, never being called by anybody on the telephone and never having anyone visit one’s residence; and
  • A lack of meaningful, extended relationships, and especially close intimacy (both emotional and physical).

Contributing Factors

The following risk factors contribute to reasons why individuals distance themselves from society.

  • Ageing – Once a person reaches an age where problems such as cognitive impairments and disabilities arise, they are unable to go out and socialise.
  • Health and disabilities – People may be embarrassed by their disabilities or health problems, such that they have a tendency to isolate themselves to avoid social interaction out of fear that they would be judged or stigmatised. Sometimes, rather than embarrassment, the disability itself and a person’s lack of a support network can be the cause of social isolation.
  • Autism – autistic and allistic (non-autistic) people communicate very differently, leading to a mutual friction when they try talking to each other. As autistic people are in a steep minority, often unable to find peers who communicate the same way they do, they are often ostracised by the majority, who mistake their direct, semantic communication style for them being purposefully arrogant, brash, and obtuse.
  • Hearing loss – hearing loss can cause communication impairment, which can lead to social isolation particularly in older adults.
  • The loss of a loved one can contribute to social isolation. Studies have shown that widows who keep in contact with friends or relatives have better psychological health. A study conducted by Jung-Hwa Ha and Berit Ingersoll-Dayton concluded that widows who had a lot of social contact and interactions lead to fewer depressive symptoms. During a time of loss social isolation is not beneficial to an individual’s mental health.
  • Living alone – A 2015 study by the National Centre for Family & Marriage Research found 13% of adults in the United States were living alone, up from 12% in 1990. The rate of living alone for people under 45 has not changed, but the rate for Americans aged 45 – 65 has increased over the past 25 years. People over the age of 65 are living alone less often.
  • Isolation may be imposed by an abusive spouse.
  • Rural isolation – In rural areas, factors such as living far apart from one another, rural flight, a negligible amount of public spaces and entertainment, and lack of access to mental health-related resources all contribute to isolation. Limited access to broadband internet and cellular activity also make it harder for those experiencing isolation to connect online or reach people.
  • Unemployment – This can begin if someone is fired, dismissed, or released from a job or workplace, or leaves one of their own accords. If the person struggles or is unable to find a new job for a long period of time (i.e. months or years) the sense of isolation can become exacerbated, especially in men.
  • Independent home worker – The tasks implied in this kind of job generally doesn’t imply social interaction in the physical level, nor going outside. Interactions and payments can be made by digital media so the person remains isolated from society.
  • Retirement – or other source of fixed income, makes it unnecessary for the person to search for a job, this situation is similar to unemployment but with better living on one hand but without the need to go outside on the other hand.
  • Transportation problems – If the person does not have transportation to attend gatherings or to simply get out of the house, they have no choice but to stay home all day, which can lead to those feelings of depression.
  • Societal adversity – Desire to avoid the discomfort, dangers, and responsibilities arising from being among people. This can happen if other people are sometimes, or often, rude, hostile, critical or judgemental, crude, or otherwise unpleasant. The person would just prefer to be alone to avoid the hassles and hardships of dealing with people. Being a part of an outgroup and social categorisation can also play a part in creating adverse circumstances that the individual may attempt to avoid depending on the policies and attitudes of the society.
  • Substance abuse can be both cause and/or effect of isolation, often coinciding with mood-related disorders, especially among those living alone.
  • Economic inequality – Poorer children have fewer school-class friends and are more often isolated. Adults on welfare, such as the Ontario Disability Support Programme prioritise their monthly entitlement towards rent and low-cost meals, leaving opportunities to socialise at restaurants and movie theatres out of the question.
  • Self-esteem – A person with a low self-esteem or lack of self love can contribute to that person’s isolation. Having a low self-esteem can cause one to overthink and stress themselves out when being around people, and can ultimately eliminate that feeling by isolating themselves. Removing this feeling can lead to an unfortunate social life in the future and can also harm potential relationships with others. According to Northeastern University, having a low self-esteem can hold us back from reaching out to making plans with other people. It can make a person feel like they’re a burden to them, therefore once again isolating themselves from going out. This can also lead a person into thinking that they are not worthy of making friends and deserve any love; and also feeling like they do not deserve to have a happy life.
  • Lockdowns, such as those imposed in 2020 and 2021 in an attempt to prevent the spread of SARS-CoV-2.

Social isolation can begin early in life. During this time of development, a person may become more preoccupied with feelings and thoughts of their individuality that are not easy to share with other individuals. This can result from feelings of shame, guilt, or alienation during childhood experiences. Social isolation can also coincide with developmental disabilities. Individuals with learning impairments may have trouble with social interaction. The difficulties experienced academically can greatly impact the individual’s esteem and sense of self-worth. An example would be the need to repeat a year of school. During the early childhood developmental years, the need to fit in and be accepted is paramount. Having a learning deficit can in turn lead to feelings of isolation, that they are somehow ‘different’ from others.

Whether new technologies such as the Internet and mobile phones exacerbate social isolation (of any origin) is a debated topic among sociologists, with studies showing both positive correlation of social connections with use of social media as well as mood disorders coinciding with problematic use.

Isolation among the Elderly

Social isolation impacts approximately 24% of older adults in the United States, approximately 9 million people. The elderly have a unique set of isolating dynamics that often perpetuate one another and can drive the individual into deeper isolation. Increasing frailty, possible declines in overall health, absent or uninvolved relatives or children, economic struggles can all add to the feeling of isolation. Among the elderly, childlessness can be a cause for social isolation. Whether their child is deceased or they did not have children at all, the loneliness that comes from not having a child can cause social isolation. Retirement, the abrupt end of daily work relationships, the death of close friends or spouses can also contribute to social isolation.

In the United States, Canada, and United Kingdom, a significant sector of the elderly who are in their 80s and 90s are brought to nursing homes if they show severe signs of social isolation. Other societies such as many in Southern Europe, Eastern Europe, East Asia, and also the Caribbean and South America, do not normally share the tendency towards admission to nursing homes, preferring instead to have children and extended-family of elderly parents take care of those elderly parents until their deaths.] On the other hand, a report from Statistics Norway in 2016 stated that more than 30% of seniors over the age of 66 have two or fewer people to rely on should personal problems arise. Even still, nearly half of all members of senior communities are at high risk for social isolation, this is especially prevalent with seniors of a lower education and within the lower economic class and compounded with diminished availability of socialising options to these lower class individuals. There has also been an observed increase in physical gait among members of these communities.

Social isolation among older adults has been linked to an increase in disease morbidity, a higher risk of dementia, and a decrease in physical mobility along with an increase in general health concerns. Evidence of increased cognitive decline has been link to an increase in social isolation in depressed elderly women. At the same time, increasing social connectedness has been linked to health improvements among older adults.

The use of video communication/video calls has been suggested as a potential intervention to improve social isolation in seniors. However, its effectiveness is not known.

Isolation and Health and Mortality

Social isolation and loneliness in older adults is associated with an increased risk for poor mental and physical health and increased mortality. There is an increased risk for early mortality in individuals experiencing social isolation compared to those who are not socially isolated. Studies have found social isolation is associated with increased risk in physical health conditions including high blood pressure, high cholesterol, elevated stress hormones, and weakened immune systems. Research also suggests that social isolation and mortality in the elderly share a common link to chronic inflammation with some differences between men and women. Social isolation has also been found to be associated with poor mental health including increased risk for depression, cognitive decline, anxiety, and substance use. Social isolation in elderly individuals is also associated with an increased risk for dementia. However, not all studies found social isolation associated with the risk of poor health outcome.

Isolation among Children and Teens

Middle school is a time when youth tend to be sensitive to social challenges and their self-esteem can be fragile. During this vulnerable time in development, supporting students’ sense of belonging at school is of critical importance. Existing research finds that adolescents’ development of a sense of belonging is an important factor in adolescence for creating social and emotional well-being and academic success. Studies have found that friendship-related loneliness is more explanatory for depressive symptoms among adolescents than parent-related loneliness. One possible explanation is that friends are the preferred source of social support during adolescence.

Scientists have long known that loneliness in adults can predispose depressive symptoms later in life. Lately, scientists have also seen that lonely children are more susceptible to depressive symptoms in youth. In one study, researchers conclude that prevention of loneliness in childhood may be a protective factor against depression in adulthood. Socially isolated children tend to have lower subsequent educational attainment, be part of a less advantaged social class in adulthood, and are more likely to be psychologically distressed in adulthood. By receiving social assistance, studies show that children can cope more easily with high levels of stress. It is also shown that social support is strongly associated with feelings of mastery and the ability to deal with stressful situations, as well as strongly associated with increased quality of life.

Demographics

Research has shown that men and boys are more likely to experience social isolation in their lives.
