There can be various reasons for social exclusion. Certain sections of society could be excluded due to housing sectors. Some live in well-spaced, industrialized, comfortable homes, while others live in dilapidated, overcrowded homes. These differences also lead to social exclusion. Urbanization also leads to social exclusion. People living in urban areas may view rural populations as less developed and a major obstacle to the development of society and as less educated. Due to their low income and lack of education, they may be socially excluded. Homeless people are also socially excluded due to their inability to provide for themselves and their families. People with intellectual disabilities in society are socially excluded because they are a deviation from society. They are not part of the mainstream of society. They have a different behavior and a different thought process that does not fit into the normality of life.
