Institute for Immigration Research

iDod Terms and Conditions


iDod Terms and Conditions are as follows:

The iDod service will be provided, free of charge, to help individuals and institutions examine the immigrant populations of their particular geography. We rely on data provided by IPUMS-USA, University of Minnesota, and the U.S. Census Bureau.

1) Expectation of Timeline

For each request we have automated the analyses as much as possible, but one important aspect of the iDod fact sheets is that they include hands-on custom tailored data. We are able to complete no more than 10 per week, and have developed a group system to let users know when they can expect their fact sheet.

2) Expectation of Use 

Ultimately, the goal of the iDod project is to create collaborations and connect people with data from their particular region or sector of interest on immigrant populations. This service will help individuals and organizations with data-based analyses.  We will be restricting the initial phase of iDod to one request per user, if you are interested in a larger project please send us an email at

Materials, logos, figures, maps, and tables cannot be separated from the fact sheets, and must be used in their original form. Data and analyses used in these fact sheets are open and free for use, please feel free to publicize, distribute, and discuss any interpretations or results you have in using iDod fact sheets.

5) Expectations for cost

The iDod fact sheets will be provided free of charge. We will be continually working to improve the iDod request form and site. If you are interested in supporting the Institute for Immigration Research, please email

6) Transfer of responsibility for terms of use for census data and ipums data

Data in each fact sheet will be combined and analyzed by the iDod Team, but the original datasets were provided by the IPUMS-USA, University of Minnesota,, and the U.S. Census Bureau Tigerline Files.

Terms Transferred from IPUMS:

: All persons are granted a limited license to use these data, but you may not charge a fee for the data if you distribute it to others.

: For more information on using the IPUMS for genealogical research see our note to genealogists.

Use it for GOOD -- never for EVIL.
