Marketplace Enrollment Maps

Updated May 2015

After the end of the second open enrollment period, new county-level estimates revealed how many Americans had picked plans on the health insurance marketplaces. The maps show the distribution of consumers in a state who enrolled in marketplace plans through federally facilitated, partnership, and supported state-based marketplaces during the 2014 open enrollment period. All maps are interactive and clicking on a county within a state displays more information on the number and proportion of consumer who enrolled there.

About the Maps

We welcome and encourage you to use this information to better understand where consumers enrolled in marketplace coverage in your community. The maps and data are presented here to help facilitate outreach during the next enrollment period, and they are not meant to measure the exact number of people who enrolled.

What do these maps show?

The maps show information on the number of individuals who enrolled in marketplace plans between November 15, 2014, and February 22, 2015, in the 35 states with federally facilitated, partnership, and supported state-based marketplaces (in other words, states where consumers enrolled in marketplace plans through HealthCare.gov).

Where do the data in these maps come from?

The Office of the Assistant Secretary for Planning and Evaluation (ASPE), in the U.S. Department of Health and Human Services (HHS), released data on the number of consumers who selected marketplace plans by ZIP code for states with federally facilitated, partnership, and supported state-based marketplaces. These estimates are available on ASPE’s website. Enroll America converted these ASPE ZIP code enrollment data into county enrollment numbers for easier interpretation. Click here for more information on our methodology.

What do these maps not show?

The maps do not show information on consumers enrolled in health coverage through state-based marketplaces, public insurance programs (including Medicaid, the Children’s Health Insurance Program [CHIP], and Medicare), or other private insurance (including off-marketplace non-group insurance and employer-sponsored coverage). The maps do not show information on changes in enrollment that occurred after February 22, including consumers who enrolled in a marketplace plan through a Special Enrollment Period (SEP) or who discontinued their marketplace plan after February 22. The maps do not show information on ZIP codes with 50 or fewer enrollments (approximately 4 percent of enrollments). ASPE excluded these numbers for privacy reasons and we followed their lead in our analysis. Lastly, the maps do not show information on the prior insurance status of enrollees, and cannot be used to estimate a decrease in the number uninsured individuals.
