About This Collection
The Health Insurance Exchanges (HIX) 2.0 collection provides overviews and raw data on the implementation of the Affordable Care Act across all 50 states, including variation and each state’s key implementation decisions.
They are produced by Leonard Davis Institute of Health Economics through a grant from the Robert Wood Johnson Foundation. The briefs provide insight into which health insurance exchange features are most effective and which factors explain state variation. The datasets were collected from primary sources such as statutes and other regulatory decisions, official gubernatorial press releases, and other reliable news sources. Note: If you are using the datasets for research purposes, please include proper citation for the data, which are provided on each dataset's page. Datasets may be combined as implementation moves forward; the date the datasets were last updated, which is specified on each dataset's page.
