In 2004 the government announced a "strategy against ghettoisation", and in the following years several other initiatives were directed specifically towards the prevailing patterns of settlements of non-western immigrants in some social housing areas. From 2010, the Danish government has published annual lists defining specific social housing areas as vulnerable based on a number of specific criteria such as unemployment rates, average income, educational levels, proportion of non-western immigrants and descendants, and crime rates. The criteria and naming of the housing areas have been changed several times. During the years 2015-2020, there was an officially named "ghetto list" for areas fulfilling certain criteria.
