"ICPSR's holdings of the historic Census data, Historical, Demographic, Economic, and Social Data: The United States, 1790-1970 (ICPSR 00003), include Census data for all the decennial years from 1790 to 1950 for counties and states, and one religious data file for the decennial year 1890. The series was developed by ICPSR and was supported by grants from the National Science Foundation. The data were collected from a variety of sources, including published and unpublished reports and computer-readable data collections prepared by the Census Bureau, the published federal decennial census reports, and data and reports from other agencies and private individuals. Included in this collection are also two datasets on economic conditions: farm land value and bank deposits, obtained from sources other than the U.S. Census Bureau." University of Maryland is a member of ICPSR.

United States census data.
IPUMS is not a collection of compiled statistics; it is composed of microdata.
"The Integrated Public Use Microdata Series (IPUMS-USA) consists of more than fifty high-precision samples of the American population drawn from fifteen federal censuses and from the American Community Surveys of 2000-2012. Some of these samples have existed for years, and others were created specifically for this database. These samples, which draw on every surviving census from 1850-2000, and the 2000-2012 ACS samples, collectively constitute our richest source of quantitative information on long-term changes in the American population."
"In 1940, educational attainment was collected for every person enumerated in the census (i.e., 100% data) and on a sample basis thereafter. At the national level, this report includes tables that show rates of educational attainment by age, sex, race, and Hispanic origin. At the regional and state levels, educational attainment data are shown by sex, race, and Hispanic origin. The tables show two attainment levels: the percent of the population 25 years and over with a high school diploma or more education and the percent with a bachelor’s degree or more."
"The Statistical Abstract of the United States, published since 1878, is the authoritative and comprehensive summary of statistics on the social, political, and economic organization of the United States.
Sources of data include the Census Bureau, Bureau of Labor Statistics, Bureau of Economic Analysis, and many other Federal agencies and private organizations."
