Migration, or geographical mobility, is an important component of demographic change. It has a major impact on population distribution as people move between cities and suburbs, metropolitan and nonmetropolitan areas, States, and regions. It is important to know the characteristics of these movers–age, race, sex, occupation, income, education, and marital status–in order to assess the impact that migration may have on the areas of origin and destination.
The mobility data in this report are estimates from the March 1981 Current Population Survey (CPS). They were derived by comparing the location of each respondent's residence in 1980 with their current residence in 1981. For comparative purposes, the text also includes some mobility data from the 1961, 1971, and 1976 surveys.
