Detailed statistics on trends in the U.S. supply and geographic distribution of personnel in eight health occupations, along with current data on selected professional characteristics, are presented. Statistical tables include combined data for the eight occupations, and groups of tables for the individual health occupations: physicians (both M.D.'s and Doctor of Osteopathy), dentists, optometrists, pharmacists, podiatrists, veterinarians, and registered nurses. The multiple occupation tables provide national trend and current figures for personnel supply and ratio to population, and certain data on percent distribution by state. In addition, related ratio and percent distribution data are presented by metropolitan areas and non-metropolitan counties. The age distribution of personnel in the eight occupations is also covered. Data are included on national trends in active personnel supply during 1950-1980, together with personnel-to-population ratios. Also provided for all eight occupations is the geographic distribution of active personnel, and their ratio to population, by region, division, and state, as of 1970, 1975, and 1980. Additional considerations include foreign medical graduates, practice characteristics by specialty, active nonfederal M.D.'s, and health occupation shortage areas. (SW)
