Often these neighbourhoods were founded out of good intentions. Many districts that later became problem neighbourhoods were founded in the 1960s and 1970s when the State wanted to provide better housing for poorer persons. As a result, big tenement buildings were built. The first tenants were mostly two-parent-families, with at least one parent working. Many were happy with their neighbourhoods, but when the unemployment rate started increasing, more and more people lost their jobs. Moreover, families who could afford it started moving into better districts and only those who could not afford to move stayed in districts such as Hamburg-Mümmelmannsberg.)
