Overview of NHGIS Datasets

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.

2015 American Community Survey

Group is comprised of 5 datasets derived from the US Census Bureau's 2015 American Community Survey (ACS) Summary Files. One dataset contains the 1-Year Summary File, providing estimates of 2015 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 2011 through 2015. NHGIS divides it into 4 datasets, each providing tables for a different set of geographic levels.

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.

1960 Census

The 4 datasets in this group provide population and housing data from the 1960 Census for several geographic levels, including census tracts where available. A limited selection of US, state and county data were entered from printed census publications for ICPSR Study 2896, Parts 38-40. (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.

1930 Census

The 22 datasets in this group provide population, housing, agriculture, and manufacturing data from the 1930 Census for several geographic levels. This includes some population and housing data for census tracts and enumeration districts where available. The US, state and county data were entered from printed census publications by the team of Michael Haines, Colgate University. Most of these data were originally published in ICPSR Study 02896, Parts 26-29 and 31. (Updates in either the ICPSR or NHGIS data may have produced incomplete correspondence.) Data in the 1930_cAg dataset were provided directly by Haines for NHGIS.

1920 Census

The 8 datasets in this group provide population, housing, agriculture, and manufacturing data from the 1920 Census for several geographic levels. This includes some population and housing data for census tracts and enumeration districts where available. The US, state and county data were entered from printed census publications by the team of Michael Haines, Colgate University. Most of these data were originally published in ICPSR Study 02896, Parts 24 and 25. (Updates in either the ICPSR or NHGIS data may have produced incomplete correspondence.) Data in the 1920_cAg dataset were provided directly by Haines for NHGIS. Tract and ED data were entered from printed census publications by the team of Andrew Beveridge, Queens College - City University of New York.

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.
