Current Population Survey (CPS) Supplements


UNICON Research

Brief Description:

The UNICON CPS Utilities is a tool to access data from the supplemental questions that are part of the U.S. Census Bureau's Current Population Survey. In addition, data from UNICON has undergone quality control measures and where possible, has been adjusted for consistency across years, helping to make the data more readily available for immediate analysis compared to raw CPS downloads.

Survey Dates:

  • ASEC 1962 - 2011
  • Education and School Enrollment 1968-2009
  • Food Security 1976-2010
  • MORG 1979-2011
  • Internet and Computer Usage 1984-2009
  • Marriage and Fertility 1971-2010
  • Tobacco Use 1967-2007
  • Veterans 1985-2011
  • Voting and Registration 1972-2008

Access data:

To access the UNICON CPS Utilities and these data, you must have a CSDE account and then access to any of the CSDE Windows terminal servers. Under the Start Menu and Progams, see the CPS Utilities.

The Current Population Survey (CPS) is a monthly survey of about 50,000 households conducted by the Bureau of the Census for the Bureau of Labor Statistics. The CPS is the primary source of information on the labor force characteristics of the U.S. population. The sample is scientifically selected to represent the civilian non-institutional population. These data represent the US as a whole and serve as part of model-based estimates for individual states and other geographic areas.

Supplementary questions are added to the CPS interview in a particular month to gather in-depth information on specific aspects of the labor force or other topics. There are about a dozen CPS supplements, several of which are available here.

  • The Annual Social and Economic supplement provides usual monthly labor force data, and in addition provides supplemental data on work experience, income, noncash benefits, and migration. Comprehensive work experience information is given on the employment status, occupation, and industry.
  • The Education and School Enrollment data are collected annually in October among a national representation of students.
  • The Food Security data consist of answers by household respondents to questions about household food expenditures, use of food assistance programs, and experiences and behaviors related to food security, food insecurity, and hunger.
  • The Historic Earner Study, or the Merged Outgoing Rotation Groups, is comprised of every household that enters the Current Population Surveys (CPS). Each household is interviewed each month for 4 months, then ignored for 8 months, then interviewed again for 4 more months. Usual weekly hours and earning questions are asked only at households in their 4th and 8th interview. New households enter each month, so one fourth of the households are in an outgoing rotation each month.
  • The Internet and Computer Usage data contain questions about the household in general (such as "Is there a computer or laptop in the household?") and about those individual household members who use the Internet.
  • The Marriage and Fertility data contain information on births and mothers’ age at last birth, collected as a national sample among women 15 to 44 years old. These data are a primary source for historical trends in fertility.
  • The Tobacco Use data contains information about changes in America's use of tobacco products as well as public attitudes about smoking.
  • The Veterans data provides estimates on the demographic and labor force characteristics of veterans 18 years old and over, including those who have a service-connected disability. The data also will identify Gulf War era veterans and Vietnam theater veterans--those who actually served in Vietnam, Laos, or Cambodia.
  • The Voting and Registration supplement is conducted every two years coinciding with major national elections, and provides a demographic, social, and economic view of the US electorate.

The UNICON CPS Utilities, a tool to access data, allow variables of interest in the supplements to be easily identified. Documentation for each variable is consolidated on a single page covering all survey years, and is hyperlinked to documentation for related variables and appendices. Each extraction is documented in a report file. Options enable filtering of observations and renaming of variables.

To download these data, you must have a CSDE account and then access to the CSDE Windows terminal server 2 (ts2). Under the Start Menu and Progams, see the CPS Utilities.
