Note. Parentheses indicate the abbreviated variable name used in tables of regression results. The number of Florida counties in our dataset is smaller than the total number of counties (67) in the state because (a) some counties do not have hospitals; (b) some small hospitals are not required to report data to the Florida AHCA, and (c) some hospitals have missing data on other variables. Missing data on the sole hospital in a county means that county is no longer included in the sample. In the regressions, counts of procedures performed in ASCs are defined separately for each of the procedures in this study; above we report the mean and standard deviation of the average count across all procedures. Data on hospital beds, teaching status, and ownership are from annual issues of the Hospital Beds and Services List published by the Florida AHCA. Population data are from the U.S. Census Bureau and the Florida Legislature's Office of Economic and Demographic Research. County income and unemployment rates are from the Bureau of Labor Statistics.
