Insurer participation in Federally Facilitated Marketplace counties from 2014 to 2019 [Color figure can be viewed at wileyonlinelibrary.com]

Notes. Data reflect all counties in 38 of the 40 states that used the Federally Facilitated Marketplace from 2014 to 2019. Alaska and Nebraska were excluded because insurers participate in their Marketplaces at the three‐digit zip code level rather than the county level. Some states only participated in the Federally Facilitated Marketplace in some years, such as Oregon (2015‐2019) and Kentucky (2016‐2019).
