Procedural History of the 1940 Census of Population and Housing
Foreword
The 1940 Census Procedural History was written as part of a project to create Public Use Sample files from the 1940 and 1950 Population Censuses. This material is based upon work supported by the National Science Foundation under Grant SES-7704135. Halliman Winsborough, Karl Taeuber and Robert Hauser were the Principal Investigators of the project. Decisions pertaining to the mode of selecting, recording, and presenting data and accompanying documentation were made by the Principal Investigators in consultation with a board of scientific advisors and the U.S. Bureau of the Census, under a general plan approved by the National Science Foundation. Specific technical judgements as well as any opinions, findings, or conclusions expressed on the basis of those judgments are the sole responsibility of the Principal Investigators and not of the Bureau of the Census or the National Science Foundation.
A Note on Language
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.
