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. Recent studies, published in 2020, use access to social activities (e.g., being able to join a local sports team) as a measurement for social integration. Comparable results are available for 23 European countries. 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 a 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 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. A
