Social integration is the process during which newcomers or minorities are incorporated into the social structure of the host society.
Social integration, together with economic integration and identity integration, are three main dimensions of a newcomers' experiences in the society that is receiving them. A higher extent of social integration contributes to a closer social distance between groups and more consistent values and practices.
Bringing together various ethnic groups irrespective of language, caste, creed, etc., without losing one's identity. It gives access to all areas of community life and eliminates segregation.
In a broader view, social integration is a dynamic and structured process in which all members participate in dialogue to achieve and maintain peaceful social relations. Social integration does not mean forced assimilation. Social integration is focused on the need to move toward a safe, stable and just society by mending conditions of social disintegration, social exclusion, social fragmentation, exclusion and polarization, and by expanding and strengthening conditions of social integration towards peaceful social relations of coexistence, collaboration and cohesion.
Integration was first studied by Park and Burgess in 1921 through the concept of assimilation. They defined it as "a process of interpenetration and fusion in which persons and groups acquire the memories, sentiments, and attitude of other persons and groups and, by sharing their experience and history, are incorporated with them in a common cultural life."
While some scholars offered an assimilation theory, arguing that immigrants would be assimilated into the host society economically, socially and culturally over successive generations, others developed a multiculturalism theory, anticipating that immigrants could maintain their ethnic identities through the integration process to shape the host society with a diversified cultural heritage.
Extending from the assimilation theory, a third group of scholars proposed a segmented integration theory, stressing that different groups of migrants might follow distinct trajectories towards upward or downward mobility on different dimensions, depending on their individual, contextual and structural factors.
Compared with other dimensions of integration, social integration focuses more on the degree to which immigrants adapt local customs, social relations, and daily practices. It is usually measured through social network, language, and intermarriage. The most commonly used indicator of social integration is social network, which refers to the connection that immigrants build with others in the host society. While some researchers use the total number of immigrants' friends as a measure, others use the frequency of interaction with friends. One thing worthy noting is that more and more studies differentiate local friends from immigrant friends because the former is considered more important in integrating immigrants into the local society than the latter.
Language is another important variable to access the degree of immigrants' social integration. A higher level in grasping local language results in more chances to communicate with local people and a better understanding of local culture. A typical question used in survey is as "Do you understand the local people's language?" In the United States, for instance, the fluency of English is an widely used indicator and can be easily found in a report on immigration.
Intermarriage is also an indicator of social integration. For those who are unmarried, they will be asked: "Would you consider marrying a local people?"; for those married, question will be like "Would you like your children to consider marrying a local people?" Answers to these questions are a good predictor of immigrants' willingness to be integrated into the host society.
In many instances education is used as a mechanism for social promotion. Neither education nor work can be ensured without a form of law. In relation to tolerant and open societies, members of minority groups often use social integration to gain full access to the opportunities, rights and services available to the members of the mainstream of society with cultural institutions such as churches and civic organizations. Mass media content also performs a social integration function in mass societies.
The 2005 documentary "Utan gränser - en film om idrott och integration" (Without Borders - A Film About Sports and Integration) was a film described by Swedish newspaper Aftonbladet as "a documentary on how to succeed with integration" of migrants into Swedish society.
The term "social integration" first came into use in the work of French sociologist Émile Durkheim. He wanted to understand why rates of suicide were higher in some social classes than others. Durkheim believed that society exerted a powerful force on individuals. He concluded that a people's beliefs, values, and norms make up a collective consciousness, a shared way of understanding each other and the world.
