Abstract

The Integrated Public Use Microdata Series (IPUMS) Complete Count Data include more than 650 million individual-level and 7.5 million household-level records. The microdata are the result of collaboration between IPUMS and the nation’s two largest genealogical organizations—Ancestry.com and FamilySearch—and provides the largest and richest source of individual level and household data.

Documentation

This dataset was created on 2020-01-10 22:52:11.461 by merging multiple datasets together. The source datasets for this version were:

IPUMS 1930 households: This dataset includes all households from the 1930 US census.

IPUMS 1930 persons: This dataset includes all individuals from the 1930 US census.

IPUMS 1930 Lookup: This dataset includes variable names, variable labels, variable values, and corresponding variable value labels for the IPUMS 1930 datasets.

Section 2

Historic data are scarce and often only exists in aggregate tables. The key advantage of historic US census data is the availability of individual and household level characteristics that researchers can tabulate in ways that benefits their specific research questions. The data contain demographic variables, economic variables, migration variables and family variables. Within households, it is possible to create relational data as all relations between household members are known. For example, having data on the mother and her children in a household enables researchers to calculate the mother’s age at birth. Another advantage of the Complete Count data is the possibility to follow individuals over time using a historical identifier.

In sum: the historic US census data are a unique source for research on social and economic change and can provide population health researchers with information about social and economic determinants.Historic data are scarce and often only exists in aggregate tables.

The historic US 1930 census data was collected in April 1930. Enumerators collected data traveling to households and counting the residents who regularly slept at the household. Individuals lacking permanent housing were counted as residents of the place where they were when the data was collected. Household members absent on the day of data collected were either listed to the household with the help of other household members or were scheduled for the last census subdivision.

Notes

• We provide IPUMS household and person data separately so that it is convenient to explore the descriptive statistics on each level. In order to obtain a full dataset, merge the household and person on the variables SERIAL and SERIALP. In order to create a longitudinal dataset, merge datasets on the variable HISTID.

• Households with more than 60 people in the original data were broken up for processing purposes. Every person in the large households are considered to be in their own household. The original large households can be identified using the variable SPLIT, reconstructed using the variable SPLITHID, and the original count is found in the variable SPLITNUM.

• Coded variables derived from string variables are still in progress. These variables include: occupation and industry.

• Missing observations have been allocated and some inconsistencies have been edited for the following variables: SPEAKENG, YRIMMIG, CITIZEN, AGEMARR, AGE, BPL, MBPL, FBPL, LIT, SCHOOL, OWNERSHP, FARM, EMPSTAT, OCC1950, IND1950, MTONGUE, MARST, RACE, SEX, RELATE, CLASSWKR. The flag variables indicating an allocated observation for the associated variables can be included in your extract by clicking the ‘Select data quality flags’ box on the extract summary page.

The Census Tree is the largest-ever database of record links among the historical U.S. censuses, with over 700 million links for people living in the United States between 1850 and 1940. These links allow researchers to construct a longitudinal dataset that is highly representative of the population, and that includes women, Black Americans, and other under-represented populations at unprecedented rates. Each .csv file consists of a crosswalk between the two years indicated in the filename, using the IPUMS histids.

Census Year 1930 Census Tracts. The dataset contains polygons representing CY 1930 census tracts, created as part of the D.C. Geographic Information System (DC GIS) for the D.C. Office of the Chief Technology Officer (OCTO) and participating D.C. government agencies. Census tracts were identified from maps provided by the U.S. Census Bureau and the D.C. Office of Planning. The tract polygons were created by selecting street arcs from the WGIS planimetric street centerlines. Where necessary, polygons were also heads-up digitized from 1995/1999 orthophotographs.

A People's History of the IE Census Data compiles the 5 feature layers of demographic data produced with the IPUMS Ancestry Full Count Data for San Bernardino and Riverside counties from census years 1900-1940. We drew all the Enumeration District (ED) geometries for these 5 decades and processed census data variables so they could be mapped by ED. Feature layers include:Basic Demographics & Race Variables (Marriage, Age and Race). This feature Layer which includes basic demographics including Race & Ethnicity data, Age, Gender and marriage. You can download the full Data dictionary here to see how individual fields were calculated and named. This feature layer includes our calculation of the most important racial/ethnic groups to settle in Inland Southern CA in the early 20th century so we can explore emerging patterns of settlement and segregation. You can see details about how we constructed these racial categories and the rationale we used for the decisions we made here in a document.Homeownership by Race which includes homeownership data by household (including numbers and percent of households who rent and own their home, and homeownership rates and renters by race for 9 racial categories. We created detailed explanation of how we constructed these racial categories and the rationale we used for the decisions we made here in a document. (See especially pages 3 & 4).Industry Labor Force Employment & Income which includes basic labor force participation information (available variables differ by decade but include employed, unemployed, and in later decades more detailed data like "at work armed forces" and NILF Housework (Not In Labor Force Housework). The feature layer also detailed industry information (which is incomplete) and includes incomes data from 1940.Birthplace Citizenship & Language - which includes birthplace data which enables users to map patterns of migration from a wide range of states and countries, citizenship status, and language spoken. The birthplace and citizenship data is very detailed for all decades, while the citizenship data is more fragmentary.Literacy & Education by Race - which includes literacy and education data that available in each decade (1900-1940), and calculations of education and literacy by race for 9 racial-ethnic categories. The literacy data for 1900-1930 is filtered to exclude young children (under 10), and the 1940 data provides more detailed data education completed data for adults 25+. All decades provide literacy and education levels for 9 historic racial categories.See the full data dictionary and the homeownership tab in the Data dictionary here.
