Census of Population, 1940 [United States]: Public Use Microdata Sample (ICPSR 8236)
Released/updated on: 2006-01-12
Geographic coverage: North Carolina, Indiana, Wyoming, Utah, Arizona, Montana, Kentucky, California, Kansas, Florida, Delaware, Pennsylvania, Mississippi, Iowa, Illinois, Texas, Connecticut, Georgia, Virginia, Maryland, Idaho, Oregon, Vermont, United States, Oklahoma, Tennessee, Maine, Alabama, Arkansas, Washington, South Carolina, Nebraska, West Virginia, Massachusetts, Colorado, Missouri, Alaska, North Dakota, Wisconsin, Nevada, Rhode Island, South Dakota, Hawaii, Minnesota, New York (state), New Jersey, Michigan, New Mexico, New Hampshire, Louisiana, Ohio
The 1940 Census Public Use Microdata Sample Project was assembled through a collaborative effort between the United States Bureau of the Census and the Center for Demography and Ecology at the University of Wisconsin. The collection contains a stratified 1-percent sample of households, with separate records for each household, for each "sample line" respondent, and for each person in the household. These records were encoded from microfilm copies of original handwritten enumeration schedules from the 1940 Census of Population. Geographic identification of the location of the sampled households includes Census regions and divisions, states (except Alaska and Hawaii), standard metropolitan areas (SMAs), and state economic areas (SEAs). Accompanying the data collection is a codebook that includes an abstract, descriptions of sample design, processing procedures and file structure, a data dictionary (record layout), category code lists, and a glossary. Also included is a procedural history of the 1940 Census. Each of the 20 subsamples contains three record types: household, sample line, and person. Household variables describe the location and condition of the household. The sample line records contain variables describing demographic characteristics such as nativity, marital status, number of children, veteran status, wage deductions for Social Security, and occupation. Person records also contain variables describing demographic characteristics including nativity, marital status, family membership, education, employment status, income, and occupation.

Released/updated on: 2006-01-18
Geographic coverage: North Carolina, Indiana, Wyoming, Utah, Arizona, Montana, Kentucky, California, Kansas, Florida, Delaware, Pennsylvania, Mississippi, Iowa, Illinois, Texas, Connecticut, Georgia, Virginia, Maryland, Idaho, Oregon, Vermont, United States, Oklahoma, Tennessee, Maine, Alabama, Arkansas, Washington, South Carolina, Nebraska, West Virginia, Massachusetts, Colorado, Missouri, Alaska, North Dakota, Wisconsin, Nevada, Rhode Island, South Dakota, Hawaii, Minnesota, New York (state), New Jersey, Michigan, New Mexico, New Hampshire, Louisiana, Ohio
This data collection contains a stratified 1-percent sample of households, with separate records for each household, each "sample line" respondent, and each person in the household. These records were encoded from microfilm copies of original handwritten enumeration schedules from the 1950 Census of Population. Geographic identification of the location of the sampled households includes Census regions and divisions, states (except Alaska and Hawaii), Standard Metropolitan Areas (SMAs), and State Economic Areas (SEAs). The data collection was constructed from and consists of 20 independently-drawn subsamples stored in 20 discrete physical files. The 1950 Census had both a complete-count and a sample component. Individuals selected for the sample component were asked a set of additional questions. Only households with a sample line person were included in the 1950 Public Use Microdata Sample. The collection also contains records of group quarters members who were also on the Census sample line. Each household record contains variables describing the location and composition of the household. The sample line records contain variables describing demographic characteristics such as nativity, marital status, number of children, veteran status, education, income, and occupation. The person records contain demographic variables such as nativity, marital status, family membership, and occupation.

Census of Population and Housing, 1980 [United States]: Summary Tape File 2B (ICPSR 8037)
Released/updated on: 2006-01-12
Geographic coverage: North Carolina, Indiana, Wyoming, Utah, Arizona, Montana, Kentucky, California, Kansas, Florida, Delaware, Pennsylvania, Mississippi, Iowa, Illinois, Texas, Connecticut, Georgia, Virginia, Maryland, Idaho, Oregon, Vermont, Puerto Rico, United States, Oklahoma, Tennessee, Maine, Alabama, Arkansas, Washington, South Carolina, Nebraska, West Virginia, Massachusetts, Colorado, Missouri, Alaska, North Dakota, Wisconsin, Nevada, District of Columbia, Rhode Island, South Dakota, Hawaii, Minnesota, New York (state), New Jersey, Michigan, New Mexico, New Hampshire, Louisiana, Ohio
Summary Tape File 2 (STF 2) files contain detailed complete-count tabulations for all persons and housing units in the United States. The STF 2B files provide summaries for states or state equivalents, state components, standard consolidated statistical areas (SCSAs) and the urban and rural portions of the SCSAs, standard metropolitan statistical areas (SMSAs) and the urban and rural portions of the SMSAs, urbanized areas, counties or county equivalents and the rural portion of the counties, minor civil divisions or Census county divisions, places of 1,000 people or more and the urban portions of any places that have been split into urban and rural components, American Indian reservations and their county portions, and Alaska Native villages. Population (or demographic) and housing items are contained in each type of file. The data are presented in two types of records. The first, record A, is presented once for each geographic area and summarizes total population and all housing units. The second, record B, is presented for the total population in each area and repeated for each race and Hispanic group in the area that meets nonsuppression criteria. Record B is presented for a maximum of 26 racial/Hispanic groups. If too few persons or housing units fall into an ethnic category in a census area, the data for that category are suppressed. There are 51 data files, one file for each state and the District of Columbia.

Census of Population and Housing, 1990 [United States]: Public Law (P.L.) 94-171 Data (ICPSR 9516)
Released/updated on: 2006-01-12
Geographic coverage: North Carolina, Indiana, Utah, Arizona, Montana, Kentucky, California, Kansas, Florida, Delaware, Pennsylvania, Mississippi, Iowa, Illinois, Texas, Connecticut, Georgia, Virginia, Maryland, Idaho, Oregon, Vermont, Puerto Rico, United States, Oklahoma, Tennessee, Maine, Alabama, Arkansas, Washington, South Carolina, Nebraska, Massachusetts, Colorado, Missouri, Alaska, North Dakota, Nevada, New York, District of Columbia, Rhode Island, South Dakota, Hawaii, Minnesota, New Jersey, Michigan, New Mexico, New Hampshire, Louisiana, Ohio
Public Law 94-171, enacted in 1975, requires the Census Bureau to provide redistricting data in a format requested by state governments. Within one year following the Decennial Census (by April 1, 1991), the Census Bureau must provide the governor and legislature of each state with the population data needed to redraw legislative districts. To meet this requirement, the Census Bureau established a voluntary program to allow states to receive data for voting districts (e.g., election precincts, city wards) in addition to standard census geographic areas such as counties, cities, census tracts, and blocks. These files contain data for voting districts for those counties for which a state outlined voting district boundaries around a set of census blocks on census maps, in accordance with the guidelines of the program. Each state file provides data for the state and its subareas in the following order: state, county, voting district, county subdivision, place, census tract, block group, and block. Additionally, complete summaries are provided for the following geographic areas: county subdivision, place, consolidated city, state portion of American Indian and Alaska Native area, and county portion of American Indian and Alaska Native area. Area characteristics such as land area, water area, latitude, and longitude are provided. Summary statistics are provided for all persons and housing units in the geographic areas. Counts by race and by Hispanic and non-Hispanic origin are also given.

School District Geographic Reference File, 1969-1970 (ICPSR 3515)
Released/updated on: 2002-11-14
Geographic coverage: United States
Time period: 1969-01-01--1970-01-01
The geographic cross-reference files have been created to allow the user to prepare additional data summaries relevant to school districts. Another use for the geographic cross-reference files is to provide the ability to equate detailed record files having school district codes with census geographic units. This capability could be used to relate administrative record summaries with census geographic data. This data collection is a school district georeference file collected during 1969-1970 that has been instrumental in aggregating First Count Summary Data by school district and can be used in interpreting the School District First Count file. This file does not contain data for the State of Maryland. Variables include state, county, minor civil division (MCD), MCD-place, census tract, block group, enumeration district (ED), population of block group, school district code, school district type, percentage of population in school district, place description, congressional district, school district name, grade range, standard metropolitan statistical area (SMSA), and government ID code.
