About this project
Income Distributions and Dynamics in America (IDDA) is a powerful resource for advancing our understanding of incomes across America. This is a collaborative research project of the U.S. Census Bureau and the Minneapolis Fed.
Frequently Asked Questions
What makes the IDDA statistics unique?
The IDDA resource and dataset is a powerful set of income-related statistics that are derived from the combination of individual U.S. tax records over a 20-plus-year horizon. IDDA statistics summarize extensive data from restricted IRS and Census Bureau records to give a novel level of fidelity to income outcomes across demographic groups in the United States. This makes insights from administrative data broadly accessible in a way that they usually are not, including descriptions of the incomes of very high earners.
