Young People in a "Problem Area" of West Berlin’s Kreuzberg Neighborhood (1980) The poor West Berlin neighborhood of Kreuzberg was regarded as a “problem area.” Approximately 57% of all neighborhood buildings had been built before 1900, 50% of residences had no bathroom and almost 70% still had stove heating. Rents were cheap as a result, and Kreuzberg attracted population groups with low incomes, above all immigrants and unemployed youth. In order to provide better occupational prospects for neighborhood youth, the Berlin Senate created a “Kreuzberg Vocational Training Center.” This program afforded young people the opportunity to acquire vocational credentials while renovating neighborhood houses.
