Part 1, the United States summary, contains 96 tables arranged under the following subject headings: employment status and class of worker, occupation, wage or salary income in 1939, industry, hours worked during week of March 24-30, 1940, months worked in 1939, and duration of unemployment. An appendix reproduces the schedule for enumeration of population and includes instructions to enumerators.
The State sections in parts 2 through 5 contain a lesser number of tables arranged under the same headings as given in the United States summary. The tables include numerous cross-tabulations and classifications according to such variables as age, color, sex, marital status, etc. These data are given for the State as a whole and for selected groups of cities, e.g., 100,000 inhabitants or more and 250,000 inhabitants or more. No county tabulations are given.
Census statistics date back to 1790 and reflect the growth and change of the United States. Past census reports contain some terms that today’s readers may consider obsolete and inappropriate. As part of our goal to be open and transparent with the public, we are improving access to all Census Bureau original publications and statistics, which serve as a guide to the nation's history.
