IPUMS Online Data Analysis System

The IPUMS online analysis system uses high-speed tabulation software developed at UC-Berkeley's Computer-assisted Survey Methods Program.

After clicking one of the samples below, you will need to specify the following to create a table:

Examples and screenshots are available in our short instructions page, or see the video tutorial.

You can also perform other analyses, such as multivariate regression, correlation matrices, and comparisons of means. See the contextual help menus for more information.

Click on any of the links below to get started! Tables are made in approximately 5-15 seconds.

Use data from multiple samples
United States, 1850-2022** Puerto Rico, 1910-2022***
American Community Survey, 2001-2022**

Considerations when using the multi-year data samples:
  • Analyses should include the "year" variable.
  • The U.S. file includes the single-year ACS samples and 1% versions of each decennial census, including the 1970 Form 1 metro sample.
  • The ACS file includes all single-year ACS samples.

** Users should proceed with caution when using the 2020 1-year ACS PUMS file and should not compare it to other ACS years in the multi-year data samples. Please see ACS and COVID-19: Guidance for Using the PUMS with Experimental Weights for more information.

*** Users should also note that due to the effects of the COVID-19 pandemic on the 2020 ACS data collection and data quality, the 2020 1-year PRCS PUMS file was not released by the Census Bureau. Thus, it is not available in the multi-year data samples.

Use data from a single sample

User Note: The IPUMS SDA system allows users to create their own variables using the "Create Variables" tab. These are not automatically removed when new versions of the IPUMS SDA samples are posted, and so created variables may be based on IPUMS data that are no longer valid. Users of created variables should pay attention to the revision history to note changes that have affected their variables and construct new variables accordingly. (The SDA dataset creation date can be found by clicking on the "Codebook" tab, while the date a user-created variable was made can be found in the list of created variables.)

** Users should proceed with caution when using the 2020 1-year ACS PUMS file and should not compare it to other ACS years in the multi-year data samples. Please see ACS and COVID-19: Guidance for Using the PUMS with Experimental Weights for more information.
