Abstract: The objective of this data collection project was to identify the presence and characteristics of Medicaid coverage for adults without dependent children for each state in the U.S. and the District of Columbia between the years of 1996 – 2014 (excluding eligibility based on disability.) Several sources were consulted to construct this dataset: 1) section 1115 Waiver Demonstration documents from the Centers for Medicare and Medicaid Services; 2) state government documents and reports; 3) reports from national health policy organizations including The Henry J. Kaiser Family Foundation, the National Academy for State Health Policy, and the National Council of State Legislators; and 4) a range of local news articles and reports. To obtain and review documents for earlier years that have not been digitized, we conducted onsite data collection at the Centers for Medicare and Medicaid Services (January 2016).
