In Germany, industrialization and urbanization went hand in hand, as individuals and entire families left the countryside and moved to cities in search of work. Living conditions were often miserable: working-class housing was dank, cramped, and overcrowded, with little fresh air or natural light. Entire families lived in narrow rooms without indoor plumbing. One such quarter on Berlin's Liegnitzer Straße in the Kreuzberg neighborhood is depicted here. The rent for this type of space would have consumed a large portion of a family’s income.
