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. 

iDod fact sheets demonstrate how immigrants contribute to the economy and society of the United States. Ultimately, the goal of iDod is to connect people with accurate data on immigrant populations. If you are interested in receiving data, please fill out an iDod Request Form.

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.

We now offer you a choice! You can receive your 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

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 immigration scholars 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.

Please contact us at with any questions or comments.  

What Goes into Making an iDod Factsheet?

In addition to providing a service to the community, iDod offers Graduate Research Assistants at the IIR the opportunity to refine their quantitative and geospatial research skills thorough fulfilling tailored data requests. In this way, the iDod service plays a key role in the IIR's goal to train and equip graduate students with the conceptual and methodological tools to be the next generation of migration researchers.

The iDod service is modeled on the academic peer review process, in which data and analysis are reviewed by Graduate Research Assistant peers along with the IIR Director, Assistant Director, and postdoctoral researcher. This thorough process of compiling a tailored factsheet ensures the accuracy and reliability of the data and analysis, while also offering Graduate Research Assistants and the IIR postdoctoral researcher opportunities to provide peer feedback and to deepen their data analysis skills, data visualization skills, and content expertise of U.S. immigration history, policies, and demographics. 

To support our work in training the next generation of migration researchers, please consider making a tax-deductible contribution.
