Williams, James M. _An American Town: A Sociological Study_ (New York, 1906). Primarily an analysis of an American community from a socio-psychological standpoint. Contains some interesting facts on growth and distribution of population. (III, 5; V, 1, 2, 3; IX, 1, 3.) Winter, Max. _Im unterirdischen Wien_, Vol. XIII in “Grossstadt Dokumente” (Berlin, 1905). A description of Vienna, showing the processes of segregation, allocation, and communication at work in the city population. (V, 1; VI, 4, 6; VII, 5; IX, 3, 4.) 3. During the latter part of the nineteenth century the expressions, “the flight from the country,” and “the drift to the city” began to be heard. The rapid increase in population of the cities was found to be due not to natural increase, i.e., excess of births over deaths, but to migration from the surrounding rural area. In America the rapid increase in the size of the cities was due chiefly to an increasing stream of European immigrants who avoided the farm but were attracted to the urban environment. Population statisticians have been alert to discover whether this process is continuing or whether a change is taking place. Improvements in rural life and conscious efforts to control the movement of population have been observed as to their possible effect on the rural-urban population equilibrium. Ashby, A.
