Confirmed: City living increases risk of psychosis

Zammit also studied individual, school and geographical characteristics that contribute to risk, and found that while the development of psychoses is driven primarily by individual risk factors — such as genetics or personal circumstances — the disconnectedness of urban living could help explain why rates of psychotic disorders were higher in the city than in rural areas. “There are some [city] neighborhoods where there is a lot of migration in and out of those areas and a lot of single parent households,” says Zammit. “We took that as reflecting poorer social networks, areas where there is less social stability.”
