Version V1

This data collection contains county-level information on total number of population and internal migration in the United States from 1930 to 1950. Demographic information is provided on race, age, and sex for the counties. There are variables that provide information by age group on the number of native-born white males and females, foreign-born white males and females, Black males and females, and males and females of other nationalities such as Indians, Japanese, and Chinese. For 1930 and 1940, the population is tabulated in five-year intervals until age 34 and in ten-year intervals thereafter. For 1950, the numbers of whites and non-whites are given by sex and age in five-year intervals. Additional variables provide information by age group on net migration of white males and females, and on Black males and females. Other variables give information on births and deaths.
