Health Policy

Business: The number of individuals in the district employed in the business sector (firms of all sizes), excluding farms and nonemployer business. These data are obtained from the U.S. Census for the U.S. Small Business Association, Office of Advocacy. Note: The U.S. Small Business Association only provides these data at the state level, and therefore these data are converted to the district level based on the number of districts in a state.

Labor: The number of union members in the district. Data on “union affiliation of employed wage and salary workers by state” are taken from the Bureau of Labor Statistics, U.S. Department of Labor. Note: The U.S. Bureau of Labor Statistics only provides these data at the state level, and therefore these data are converted to the district level based on the number of districts in a state.

Physicians: The total number of individuals in the district employed in the “offices of physicians” in the district (North American Industry Classification System code 6211). These data are taken from the U.S. Census Bureau, 1997 Economic Census (NAICS). Note: The U.S. Census Bureau provides these data at the county level, and therefore these data are converted to district-level data based on county-to-congressional district maps.
