Social class
Effect on the population

Societies with large class differences have a greater proportion of people who suffer from mental health issues such as anxiety and depression symptoms. A series of scientific studies have demonstrated this relationship. Statistics support this assertion and results are found in life expectancy and overall health; for example, in the case of high differences in life expectancy between two Stockholm suburbs. The differences between life expectancy of the poor and less-well-educated inhabitants who live in proximity to the station Vårby gård, and the highly educated and more affluent inhabitants living near Danderyd differ by 18 years.

Similar data about New York is also available for life expectancy, average income per capita, income distribution, median income mobility for people who grew up poor, share with a bachelor's degree or higher.

In class societies, the lower classes systematically receive lower-quality education and care. There are more explicit effects where those within the higher class actively demonize parts of the lower-class population.
