Shortly after the 1920 census data became available, the Division of Farm Population and Rural Life began preparing a series of maps showing graphically the state-of-birth data for certain native-born elements of the population in a few areas. The interest shown in these maps warranted an expansion of the sample. Thus, as rapidly as available resources permitted, the assembling of census data for the native white population of each state was completed including that for 1930, maps were prepared for a number of the states, and photographic prints of these maps were given a limited circulation. During the winter of 1933-1934, a grant of funds from the Civil Works Administration made possible the preparation of remaining maps. To make these maps more widely available, they were reduced in size and are assembled in this publication.
