About The Study: In this study of Marketplace enrollment data from 2015 to 2021, race and ethnicity information were missing for 32% of enrollees. Further analysis suggested that enrollees with missing data were disproportionately Black and Hispanic and that the Marketplace may serve a more diverse population than indicated by self-reported data.

Authors: D. Keith Branham, Dr.P.H., M.P.H., of the U.S. Department of Health and Human Services in Washington, D.C., is the corresponding author.
