Note 59 — Chapter IX · Disruption of the Family.
Meta Stern Lilienthal translation
The Prussian census of 1900 has shown that in Prussia there are 3,467,388 persons not related to the families in whose midst they live. In the entire state about one-quarter of these non-related members of the households consisted of strange boarders and lodgers; in the rural districts they constituted only one-seventh, but in the cities one-third, and in the capital, Berlin, more than one-half.—G. v. Mayer, “Statistics and Social Science.”
