KFF has conducted this annual survey of private and non-federal public employers with three or more workers since 1999. The survey tracks trends in employer health insurance coverage, the cost of that coverage, and other topical health insurance issues. Findings are based on a nationally representative survey of public and private employers with ten or more employees, including those who respond to the full survey and those who indicate only whether or not they provide health coverage.
The archive includes surveys conducted in partnership with the Health Research and Education Trust through 2017 and a small business supplement of the 1998 survey conducted by KFF. Access each report below.
NOTE: In 2025, the sample was updated to firms with 10 or more employees, therefore removing firms with 3-9 workers. This methodological change most noticeably impacts employer-weighted estimates, such as the firm offer rate statistic. However, historical estimates of other key statistics may differ slightly compared to previous reports. For more information, see the Survey Design and Methods Section in the 2025 Report.

NOTE: In 2011, our methodology for calculating employer weights was updated. Statistics such as the percentage of firms offering health benefits or the percentage of firms offering retiree coverage are updated in the preceding reports. Statistics based on the percentage of covered workers were not affected by this change. Most changes were not statistically different. For more information, see the Survey Design and Methods Section in the 2011 Report.
