DATA TOOL | US Unauthorized Population by State

The State Data Tool allows researchers to obtain estimates and characteristics on undocumented immigrants for selected states within the United States. The tool is available at

To obtain the national estimates, do not click on any state. To obtain state estimates, click on the specific state or states. If you select multiple states, the tool will aggregate those states (sum them together), so that you can use the tool to get regional numbers. 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.
