Marketplace Products

The Office of Enterprise Data and Analytics, within the Centers for Medicare aqnd Medicaid Services (CMS), has developed a set of information products and analytics examining 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 platform (38 states in 2016). Each product clearly defines the population. Caution is recommended when comparing annual data as the definitions for some variables have changed from one reporting period to another. These changes are noted in the affected products.
