This data collection consists of modified records from CENSUS OF POPULATION AND HOUSING, 1970 [UNITED STATES]: PUBLIC USE SAMPLES (ICPSR 0018). The original records consisted of 120-character household records and 120-character person records, whereas the new modified records are rectangular (each person record is combined with the corresponding household record) with a length of 188, after the deletion of some items. Additional information was added to the data records, including typical educational requirement for current occupation, occupational prestige score, and group identification code. This version also differs from the original public use census samples in other ways: all ages for all respondents were included, 1 percent of the majority from each 1970 file was included, 10 percent of the Black population in each file was included, and Mexican Americans outside the five southwestern states of Arizona, California, Colorado, New Mexico, and Texas were included, but were identified as "other Hispanics." Other variables provide information on the housing unit, such as occupancy and vacancy status of house, tenure, value of property, commercial use, rent, ratio of property value to family income, availability of plumbing facilities, sewage disposal, complete kitchen facilities, flush toilet, water, and telephone. Data are also provided on household characteristics such as the size of family, the presence of roomers, boarders, or lodgers, and household relationships. Other demographic variables specify age, sex, place of birth, income, marital status, race, citizenship, and ratio of family income to poverty cutoff level. This collection was made available by the National Chicano Research Network of the Institute for Social Research, University of Michigan.

This data file contains school district-level data from the following two sources: (1) the National Institute of Education (NIE) Special Tabulations of 1970 Census data, retabulated to 1973-1974 school district boundaries, and (2) the 1970 Census of Population and Housing Fifth Count data. The data in this collection were extracted from the 1976-1977 Merged Federal File produced by AUI Policy Research. Since some districts on the 1976-1977 Merged Federal File had consolidated by 1978-1979, NIE Special Tabulations data for these districts were combined. The Census data file was created in three steps. First, a skeleton file was created, containing one record for each school district on the 1978-1979 Merged Federal File. Each record on the skeleton file contained those data items in the School District Identification segment on the Merged Federal File. Second, the NIE Special Tabulations data were merged by the Office of Education (OE) state code and Local Education Agency (LEA) code to the skeleton file. Finally, Census Fifth Count records were merged by OE state code and LEA code to the skeleton file.

One in five housing units in 1970 received a long form containing supplemental sample questions. There were two versions of the long form, with different inquiries on both housing and population items; 15 percent of households received one version, and 5 percent received the other. Six independent 1 percent public use samples were produced for 1970, three from the 15 percent questionnaire and three from the 5 percent questionnaire. IPUMS-International uses the "Form 2 Metro" sample.

The 1970 Census School District Data Tape (SDDT) User's Guide was designed to complement the 1970 Census User's Guide prepared by the United States Census Bureau. The School District Data Tape (SDDT) created by the National Center for Education Statistics is a recompilation of the 1970 Census Fourth Count Population data, providing data tables for each school district in the country with 300 or more students. The preparation of the School District Data Tape required three major steps: (1) overlaying school district boundaries on census maps, (2) creating a geo-reference tape indicating the percent of each census area falling within each school district, and (3) merging the geo-reference tape with the 1970 Census Fourth Count Population Files A (Traced Areas) and B (Minor Civil Divisions). Some of the major uses of the School District Data Tape include: allocation of federal funds, desegregation planning, bilingual and minority special education planning, preschool and child care planning, facility planning, redistricting, urban-suburban-rural analyses, mobility analysis, social and economic inequality among school districts, and school children profiles. In addition to these uses, most state education agencies will find data by school district of value in allocating federal and state aid to school districts and in the evaluation of the inequality of property taxes as a basis for financing elementary and secondary education. The School District Data Tape matches, as closely as possible, the format of the Fourth Count (Population) Summary tapes supplied by the Census Bureau.

Census Tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity that are updated by local participants prior to each decennial census as part of the Census Bureau's Participant Statistical Areas Program. The Census Bureau delineates census tracts in situations where no local participant existed or where state, local, or tribal governments declined to participate. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of statistical data.

Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. A census tract usually covers a contiguous area; however, the spatial size of census tracts varies widely depending on the density of settlement. Census tract boundaries are delineated with the intention of being maintained over a long time so that statistical comparisons can be made from census to census. Census tracts occasionally are split due to population growth or merged as a result of substantial population decline.

This extraction of data from 1970 decennial Census files (CENSUS OF POPULATION AND HOUSING, 1970 UNITED STATES: SUMMARY TAPE FILES 4A, 4B, 4C (ICPSR 9014, 8127, 8107) and STF 5A, 5B, and 5C) was designed to provide a set of contextual variables to be matched to any survey dataset that has been coded for the geographic location of respondents, such as the PANEL STUDY OF INCOME DYNAMICS, 1968-1988 (ICPSR 7439). This geographic area data can also be analyzed independently with neighborhoods, labor market areas, etc., as the units of analysis. Over 120 variables were selected from the original Census sources, and more than 100 variables were derived from those component variables. The variables characterize geographic areas in terms of population counts, ethnicity, family structure, income and poverty, education, residential mobility, labor force activity, and housing. The geographic areas range from neighborhoods, through intermediate levels of geography, through large economic areas, and beyond to large regions. These variables were selected from the Census data for their relevance to problems associated with poverty and income determination, and 80 percent were present in comparable form in both the 1970 and 1980 Census datasets.

This documentation has been created by ICPSR for the restricted version of Census 1970 distributed by the Bureau of the Census. The restricted data is based on questions from the long form questionnaire, and was collected from one in six households in the United States. Topics covered include income, ancestry, citizenship status, home values, commute time to work, occupation, education, veteran status, language ability, migration, place of birth, and many others. The documentation available here provides files summaries, variable information, and facilitates sorting of the data by race or by a wide variety of geographical units. ICPSR is not distributing the restricted data, only the documentation for it. Users who wish to access the restricted data can find more information at the Michigan Census Research Data Center Web site. Users should also note that the data for the public versions of Census 1970 are available from ICPSR.

Data of Demography 1970 consists of three excerpts from the Census of the Population 1970. The first part is a description of the total population by age, marital status and sex with one record/county, administrative district, parish, district, population center. The second describes foreigners and foreign born in administrative districts larger than 50.000 inhabitants and X percent foreigners. One record/person with data on age, sex, marital status, administrative district, population, percent foreigners and citizenship. The third consists of all foreigners. One record/person with information about county, administrative district, population center, sex, marital status, age, country of origin and citizenship. The persons are not identifiable by numbers.

This file contains data summarizing a third-count tally of the 1970 Census of Population and Housing. The data corresponds to the tables found in the Census of Housing, Vol. 3, Block Statistics. The Third Count Summary is the third of three series presenting complete-count data.
