1930 Image Gallery
As of April 1, 1930, there were 123 million people living in the United States. Because of the stock market crash of 1929, which resulted in the Great Depression, the Census Bureau rushed to release unemployment data from the 1930 Census. The data were viewed as being too low, so a special unemployment census was conducted in January 1931. Another unemployment census was conducted in 1937, which provided the Census Bureau the opportunity to test new statistical sampling procedures.
