Site explanation: "Since the first census in 1790, the U.S. Census Bureau has collected data using a census 'schedule,' also called a 'questionnaire.' "
Census Instructions
It is important to know, for each census, what was asked and how terms were defined in order to understand the data. These changed from census to census, so this page is an important one when beginning research.
Links to copies of the actual instructions for each U.S. Decennial Census of Population. Includes a quick overview to changes to the instructions.

Census Note on Language

From the U.S. Census Bureau site (posted on several pages for historic censuses):

"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."
