The MEPS Insurance Component (MEPS-IC) collects data on health insurance plans obtained through employers. Data collected include the number and type of private insurance plans offered, benefits associated with these plans, premiums, contributions by employers and employees, eligibility requirements, and employer characteristics. The list sample is a nationally representative random sample of private establishments and governments. The private business sample is selected from the Business Register. Governments are selected from the Governments Integrated Directory (GID), a list of state and local government units maintained by the Census Bureau's Bureau's Economic Reimbursable Surveys Division. The list of private establishments is stratified by state and then by classes defined by establishment and enterprise employment. Sample sizes within strata are set so that strata that account for large shares of employment had relatively large sample sizes, though sample shares rise less than proportionately with employment. Sample sizes within strata are set to provide large enough samples to estimate totals for employees working in 40 states, as well as enough sample in the other states to provide estimates for the nation as a whole. There are 31 states for which sample sizes are adequate for state estimates in each year. The other twenty states receive a smaller sample allocation on a rotational basis. In any given year, 9 of those 20 have large enough samples to support state-level estimates, while the remaining 11 have smaller samples. Use of this dataset requires approval from the Agency for Healthcare Research and Quality. The Census Bureau will coordinate all additional necessary reviews.
