The 1930 census was a nationally based survey of that year’s population numbers for the people of the United States by the government of that country. In this regard, the U.S. 1930 census was the fifteenth to be carried out in the nation. The 1930 census, as with most of the censuses that have occurred in the country after a date, was under the administrative purview of the Census Bureau. Today, the multitude of documentation generated by the 1930 census taking can be accessed through the storage medium of the Integrated Public Use Microdata Series, as well as through the National Historical Geographic Information System.
The 1930 census is held, in terms of historical interest, to be significant in that it confirms and continues the finding produced by the previous U.S. census, which, as is the case for United States national surveys, came ten years before it, in the 1920 period. In this respect, the 1930 census revealed that the increase in the U.S. population, though continuing to some extent, reversing from the rate at which it had been increasing between ten year intervals at the beginning of the century.
Just as the 1910 and 1920 censuses showed the U.S. population rate of increase falling by around 5% in comparison with the consistency between the 1910 and 1900 census, a comparison of the 1920 and 1930 census showed a fall of around 5% in the extent to which the U.S. population increased, suggesting declining amounts of population to the country and stabilizing circumstances for population growth
