User Feedback / Errors

We also welcome suggestions and feedback about errors, inconsistencies, or ambiguities in the data and documentation. If you discover a significant error, we will happily send you a complimentary IPUMS mug. Please send feedback to atusdata@umn.edu

Tell us how you used MTUS

We request that users tell us about any publications, research reports, or educational materials they have created using the MTUS data or documentation. In the future, we will create a bibliography containing references to publications, presentations, and works in progress that use MTUS-X data. We welcome information (including author, title, date, and other standard citation material, such as journal name and volume) about books, educational materials, or papers to satisfy a course requirement that draw upon MTUS data or documentation. Thanks for your help!
