The Medical Expenditure Panel Survey (MEPS) is a set of large-scale surveys of families and individuals, their medical providers (doctors, hospitals, pharmacies, etc.), and employers across the United States. MEPS collects data on the specific health services that Americans use, how frequently they use them, the cost of these services, and how they are paid for, as well as data on the cost, scope, and breadth of health insurance held by and available to U.S. workers. The two major components of MEPS are the Household Component and the Insurance Component.
The University of Michigan Health and Retirement Study (HRS) is a longitudinal panel study that surveys a representative sample of approximately 20,000 Americans over 50 years old. Core surveys take place every two years, with additional topics covered in off-year surveys. Data collected through a mix of phone and face-to-face interviews provides a comprehensive look at the changing experiences of older Americans on a range of topics including physical and mental health history and status, cognition, family structure, health care utilization and costs, financial status, and employment history and retirement plans. Interviews are supplemented with information from physical measurements, biomarker and genetic data, and linkages to administrative data.
