In this issue brief, we examine the plans and premiums available at the county level. Because some plans may not serve all counties within a rating area, county-level analysis provides a better approximation of plan availability. Note that analysis in previous ASPE briefs on Marketplace premiums was typically at the rating area level; therefore, numbers in this brief should not be compared against those in previous briefs using rating-area analysis.
Our analysis of premiums in Tables 2-5 considers only current enrollees whose 2014 Marketplace plan is available in 2015, based on each plan’s unique ID code. Consumers can be auto-enrolled into similar coverage even if their exact plan is not available for the next year.
