 From the 1930, the district was used to house "abnormals", under the supervision of police, social work and medical workers.While it was intended to have an educational function, training its resident to integrate into society and eventually move out of Ondiep, this seldom happened, adding to the district's reputation as a ghetto within Utrecht.The population has traditionally been highly sedentary with a high percentage of people being born there continuing to live in the district after marriage.
