Monitoring the metropolitanization process.

Alternative approaches have led to different interpretations of the metropolitanization process in the United States. We identify and illustrate several methods and procedures for monitoring metropolitan-nonmetropolitan population change using the 1950-1980 U.S. decennial censuses. Two basic approaches are compared: constant area approaches and component methods. In addition, we assess the effects of changing metropolitan definitions on metropolitan-nonmetropolitan growth. The results clearly reveal that the underlying mechanics of metropolitanization not only are complex but have changed substantially during the 1950-1980 period. We conclude with observations regarding the use of these procedures in future research.

Racial concentration and segregation across U.S. counties, 1950-1980.

By presenting race-specific population concentration indexes for U.S. counties for the 1950-1980 period, this paper updates and extends previous analyses of 1900-1974 patterns of population concentration by Duncan et al. (1961) and Vining and Strauss (1977). Declines in population concentration persisted through 1980 only among the white population. Blacks continued to experience increases in population concentration between 1970 and 1980. These racially divergent patterns of concentration in the 1970s have translated into increases in segregation between blacks and whites across U.S. counties.
