NHGIS summary tables are organized into datasets distinguished by the years, geographic levels and topics they cover; by the data source and survey coverage (e.g., sample-based vs. 100% count); and by the breakdown variables available.
NHGIS datasets are in turn organized into dataset groups, each of which corresponds to a single census program or to specific data measurement or release years.
NHGIS Dataset Groups
2021 American Community Survey
Group is comprised of 5 datasets derived from the US Census Bureau's 2021 American Community Survey (ACS) Summary Files. One dataset contains the 1-Year Summary File, providing estimates of 2021 population and housing characteristics for areas with a population of 65,000 or more. The 5-Year Summary File provides estimates of average characteristics from 2017 through 2021. NHGIS divides it into 4 datasets, each providing tables for a different set of geographic levels.

2020 American Community Survey
Group is comprised of 4 datasets derived from the US Census Bureau's 2020 American Community Survey (ACS) 5-Year Summary File, which provides estimates of average characteristics from 2016 through 2020. NHGIS divides the Summary File into 4 datasets, each providing tables for a different set of geographic levels. Note: For most other ACS release years, NHGIS also includes data from the 1-Year Summary File, but the 2020 ACS release included only 1-Year Experimental Data Tables, which employ an experimental weighting scheme to address deficiencies in the 2020 sample due to the COVID-19 pandemic. NHGIS has not added the Experimental Data Tables because they include only nation- and state-level data for a smaller range of subjects than standard 1-Year Summary Files.

2000 Census
Group is comprised of 26 datasets derived from US Census Bureau summary files. 8 datasets correspond to 2000 Summary Files 1 to 4, including 2 supplemental files for SF1 and SF2. SF1 and SF3 were both divided to separate out the smaller number of tables available at census block and block group levels. The tables in the PL 94-171 Redistricting File are repeated in SF1 for most geographic levels, so the NHGIS PL 94-171 dataset only provides data for geographic levels not in SF1. The remaining datasets in the group all correspond to files from the Census 2000 Special Equal Employment Opportunity (EEO) Tabulation.

(Updates in either the ICPSR or NHGIS data may have produced incomplete correspondence.) Tract data are drawn from 2 sources (resulting in some redundancy): an electronic data file produced by the Census Bureau in 1971 and the 1960 Elizabeth Mullen Bogue File (ICPSR Study 2932), which was transcribed from printed census reports.

1970-2007 Vital Statistics
Group is comprised of 1 dataset of vital statistics for the U.S., states, and counties in 1970, 1975, 1980, and 1985, and annually from 1990-2007. The data are derived from the USA Counties database of the U.S. Census Bureau, which includes birth and death data from the National Center for Health Statistics (NCHS) and population estimates from the U.S. Census Bureau Population Estimates program. WARNING: Where county boundary changes occurred, the population estimates may be based on *different* county boundary definitions than the birth and death counts. In some cases, NHGIS has attempted to standardize the counts and rates to describe consistent county definitions. Elsewhere, NHGIS supplies a note to indicate where inconsistencies may occur. In these cases, the reported birth and death rates may be inaccurate and should be interpreted with caution.

1867-2010 Vital Statistics
Group consists of 1 dataset provided by the National Center for Family and Marriage Research (NCFMR) at Bowling Green State University. NCFMR researchers derived the 2000 and 2010 data from county court record information obtained through individual state or county agencies. They derived the earlier data from print reports from the U.S. Bureau of Labor (1867-1886), the U.S. Census Bureau (1890, 1900, 1916, 1922-1932), the National Office of Vital Statistics (1949-1950, 1952, 1957-1958), and the National Center for Health Statistics (1959-1987). NHGIS researchers reformatted the data and enriched the metadata for redistribution.

1934 Special Census of Chicago
The 1934 Special Census of Chicago was conducted by the Chicago Census Commission (not the US Census Bureau) in January of 1934 with the aid of over 2,800 men and women put to work by the Civil Works Administration . The purpose of this tract-level census was, as then Mayor Edward J. Kelly described, "...to know exactly what had been the effects of the depression upon changes of residences, occupancy of dwellings, housing needs, health of the people, etc." (Charles Shelton Newcomb, Richard O. Lang, Chicago Census Commission. Census Data of the City of Chicago, 1934. Chicago, IL: The University of Chicago Press, 1934). The data were digitally transcribed by the team of Andrew Beveridge, Queens College - City University of New York.

1925 Special Census of Detroit
The 1925 Detroit City Census was conducted by the Detroit Board of Education (BOE) and not the US Census Bureau. While the BOE conducted an annual census of school-age population for appropriating state school funds, city officials suggested and approved a census of the entire population to benefit other city departments. The US Census Bureau provided a supervisor to ensure the data were also acceptable to the federal government. The city was divided into 570 census zones, but no data were tabulated for two of these (2162 and 2165). It is possible that these zones had no population, but the source documentation provides no explanation. The data were digitally transcribed by the team of Andrew Beveridge, Queens College - City University of New York.
