This report presents 2000 earnings and employment data by state and county for persons covered under the Social Security and Medicare programs.

The data show, by sex, race, and age, the number of wage and salary workers and self-employed persons, the amount of their taxable earnings, and the amount they paid in Social Security and Medicare contributions. The information in this publication is a rich data source for researchers and policymakers who are interested in studying the primary revenue source for the Social Security (Old-Age, Survivors, and Disability Insurance) and the Medicare (Hospital Insurance Part A) programs. When coupled with the Social Security Administration publication OASDI Beneficiaries by State and County, these data are valuable for studying the impact of the Social Security program and are used for this purpose in academia, private industry, and state governments.

Greg Diez, Fred Galeas, Bill Kearns, Randall Miles, and Shirley Piazza in the Division of Earnings Statistics and Analysis are the team that designed, compiled, programmed, validated, and reviewed the data for this publication. Rich Mason and Dana Sheild in the Office of Systems wrote the computer programs to produce the source data from SSA's programmatic data files. Emil Loomis designed the cover, Celine Houget edited the report, and Laurie Brown prepared the electronic versions for the Web.
