COMPONENTS OF POPULATION CHANGE IN SUBURBAN AND CENTRAL CITY POPULATIONS OF STANDARD METROPOLITAN AREAS: 1940 TO 1950.

This paper shows the sources of population change in standard metropolitan areas and compares the change in central cities and suburban areas resulting from each source. Five steps in the estimating procedure are stated and the operations described. It is shown that between 1940 and 1950 the central cities, as a group, lost population through net migration. Their moderate growth was due to annexation and to a natural increase rate which more than made up for the net migration loss. The suburban rings gained 26 per cent through net migration. There was much variation among the metropolitan areas and among their central and suburban parts in the components of their growth. Population change in the Chicago Standard Metropolitan Area in the 1930-40 and 1940-50 decades is illustratively analyzed to show the color, sex, and age components. [ABSTRACT FROM AUTHOR]
