Methodology

EBA, in partnership with business intelligence data analytics firm miEdge, reveals the least competitive large-group health insurance marketplaces by state (including the District of Columbia and Puerto Rico) based on Form 5500 Schedule A reporting data on premiums as of September 2015.

The combined rank number considers the following data points: 1) how much of the large-group market is controlled by one insurance carrier and 2) how much of the large-group market is controlled by the top five insurance carriers. This combination provides the best indication of how much each market is dominated by one carrier by adding the percent market share of the top carrier to the percent market share of the top five carriers.
