iDod: Data on immigrants, customized for you 

Immigration Data on Demand (iDod) provides academics, policy-makers, and the public with unbiased and objective information related to immigrants and immigration in the United States. This service is intended to help individuals and institutions examine the immigrant populations of their particular geography and connect people with accurate data on immigrant populations. Through fulfilling tailored iDod data requests, Graduate Research Assistants at the Institute for Immigration Research (IIR) follow a rigorous methodology and have the opportunity to refine their quantitative and geospatial research and analysis skills with hands-on application.

If you are interested in receiving data, please fill out an iDod Request Form. We currently offer data as:

  • a fact sheet with data, maps, charts, and analysis OR
  • an Excel spreadsheet with your data in a format that you can adapt for your own purposes (download an example here)

Unlike many available services, iDod provides this data free of charge and will personalize each request.  For more information, browse our Terms & Conditions and library of previously produced fact sheets and spreadsheets. To support our work in continuing to offer this service free of charge to the public, please consider making a tax-deductible contribution.

NOTE: We occasionally receive requests from students who want to use iDod to complete a homework assignment. The IIR is dedicated to providing the next generation of migration researchers with the tools they need to conduct research into immigrant communities. We will not do students' assignments for them, but we can provide the information they need to perform the work themselves. To get started, check out our growing list of resources for migration researchers.

Please contact us at with any questions or comments.
