The Office of Enterprise Data and Analytics, within the Centers for Medicare & Medicaid Services (CMS), has developed a set of information products that examine enrollment activity in the Health Insurance Marketplaces (the Marketplaces). The Marketplaces were established in 2014 and allow individuals to shop for health insurance and dental plans. While some of the data products available here include data for all 50 states and the District of Columbia, other products focus only on states that utilize the Healthcare.gov platform. Each product clearly defines the population. Caution is recommended when comparing data from one year to another as the definitions for some variables have changed over time. These changes are noted when applicable.
