In March 2010 Public Opinion Research Centre focused on social distance among the major population and different social groups. Social distance was measured by a specific question: people should pick from a list of 15 different groups those, which they would not like to have as neighbours. The biggest distance was noticed towards drug addicts (86 % of Czechs would not want them to be their neighbours), people addicted to alcohol (79%), people with criminal past (75%) and also people with mental disease (60%).
