The PUMA Data Tool allows researchers to obtain estimates and characteristics on the eligible-to-naturalize population by public use microdata sample areas (PUMA) areas – sub-state areas in the United States that have a minimum population of 100,000. The tool is available at http://data.cmsny.org/puma.html. At this time, CMS is no longer accepting requests for PUMA-level data on the US unauthorized population. If you have questions, please contact email@example.com.
PUMAs are a specialized geography created by the US Census Bureau in partnership with states, so that microdata samples can be used to create user-defined data sets. Similar to the State Data Tool, users can use the PUMA tool to select one or multiple PUMAs in order to aggregate estimates. Results appear at the bottom of the page. To save your data, click on either the Excel or Word icons located below each map to download the file and save to your local computer.
Note, however, that the geography of a PUMA will not necessarily “match” an existing city or county. As you hover over a PUMA on the map, descriptive names of the PUMA will appear to describe the general boundaries for that PUMA. In addition, you can type in descriptive names in the search bar in order to identify cities or PUMAs, and the map will zoom to that area.
Although these PUMA labels can help users identify areas, we also recommend that users learn more about this geography at the following links to the Integrated Public Use Microdata Series (IPUMS) at the Minnesota Population Center of the University of Minnesota:
