The Current Population Survey (CPS) Computer and Internet Use Supplement collects household information from all eligible CPS households, as well as person information from household members 3 years old and over. Data are provided about the household's computer and internet use and about each household member's use of the internet from any location in the past year. It also asked about a random respondent's use of the Internet. The universe consists of all persons in the civilian noninstitutional population of the United States living in households. The probability sample selected to represent the universe consists of approximately 56,000 households.

The Civic Engagement Supplement of the Current Population Survey asks about respondents' involvement in their communities and communication with their family and friends. These questions are asked of respondents 18 years of age and older in all available samples except 2008, where questions were asked of respondents age 15 and older. The data offer such information as: level of participation in organized groups, extent of political action and knowledge, extent of connections with other community members, and how often individuals get news and information from various media sources.

From 2017 and onwards, the CPS Civic Engagement Supplement was merged with the CPS Volunteer Supplement to become the CPS Volunteering and Civic Life Supplement.

The Tobacco Use Supplement to the Current Population Survey (TUS-CPS) is a National Cancer Institute (NCI) sponsored survey of tobacco use that is administered as part of the U.S. Census Bureau's Current Population Survey. The Centers for Disease Control and Prevention (CDC) was a co-sponsor with NCI from 2001-02 through 2006-07.

The Tobacco Use Supplement-Current Population Survey (TUS-CPS) has served as a key source of national, state, and sub-state data on tobacco use behaviors, attitudes, and policies in the United States. The TUS is conducted every 3-4 years as part of the CPS, a monthly survey conducted by the U.S. Census Bureau for the U.S. Bureau of Labor Statistics.

The Annual Demographic Survey or March CPS supplement is the primary source of detailed information on income and work experience in the United States. Numerous publications based on this survey are issued each year by the Bureaus of Labor Statistics and Census. A public-use microdata file is available for private researchers, who also produce many academic and policy-related documents based on these data.

The Annual Demographic Survey is used to generate the annual Population Profile of the United States, reports on geographical mobility and educational attainment, and detailed analysis of money income and poverty status. The labor force and work experience data from this survey are used to profile the U.S. labor market and to make employment projections.

To allow for the same type of in-depth analysis of hispanics, additional hispanic sample units are added to the basic CPS sample in March each year. Additional weighting is also performed so that estimates can be made for households and families, in addition to persons.
Provide data concerning family characteristics, household composition, marital status, education attainment, health insurance coverage, foreign-born population, previous year’s income from all sources, work experience, receipt of noncash benefit, poverty, program participation, and geographic mobility.

The CPS Volunteer Supplement was a national survey conducted to obtain information about the number of individuals in the U.S. involved in unpaid volunteer activities, and to measure the frequency with which individuals volunteer. The survey also identifies the types of organizations that facilitate volunteerism, and the types of activities in which volunteers participate. In 2016, the supplement changed to the Volunteer and Civic Life Supplement (RDG 855) to include additional questions. 

Data are provided on participation in volunteer activities during a one-year period from September 1 of the previous year to the date of the interview, the frequency of that activity, types of organizations volunteered for, and the types of activities for volunteer service.  Data are also provided on participation in volunteer activities in a foreign country and in volunteer activities more than 120 miles from home.  Data are also provided on whether or not donations of money, assets, or property valued at 25 dollars or more were made in the past year to charitable or religious organizations.

The Current Population Survey Food Security Supplement (CPS-FSS) is the source of national and State-level statistics on food insecurity used in USDA's annual reports on household food security. The CPS is a monthly labor force survey of about 50,000 households conducted by the Census Bureau for the Bureau of Labor Statistics. Once each year, after answering the labor force questions, the same households are asked a series of questions (the Food Security Supplement) about food security, food expenditures, and use of food and nutrition assistance programs. Food security data have been collected by the CPS-FSS each year since 1995.

Voting and Registration data have been collected biennially in the November Current Population Survey (CPS) since 1964. The statistics presented are based on replies to survey inquiries about whether individuals were registered and/or voted in specific national elections. For the purpose of these estimates, election types are considered to be either Congressional (e.g. 2002, 2006, etc.) or Presidential (e.g. 2004, 2008, etc.). This national survey is conducted to produce a comprehensive set of statistics on voter and nonvoter characteristics as well as current voter trends, distinct from independent surveys, media polls, or other outside agencies. The universe for this survey is persons 18 years of age and older in each household that was eligible for the basic Current Population Survey (CPS). This survey is a proxy response survey and is sponsored by the United States Census Bureau.

The Federal Deposit Insurance Corporation sponsors the National survey of Unbanked and Underbanked Households to collect data on the number of U.S. households that are unbanked and underbanked, their demographic characteristics, and their reasons for being unbanked and underbanked. This survey was conducted by the U.S. Census Bureau as a special supplement to the Current Population Survey (CPS). The first survey was conducted in January 2009 and the second was conducted in June 2011. With the rich demographic and geographic data available through the CPS, this survey continues to present a wealth of previously unavailable data on unbanked and underbanked households at the national, state, and large metropolitan statistical area (MSA) levels.
