The increasing supply of physicians in US urban and rural areas, 1975 to 1988.

BACKGROUND: Despite the rapid growth of the US physician supply since the mid-1970s, it remains unclear whether physicians have spread into the most rural areas of the country. This report examines the urban-rural distribution of physicians between 1975 and 1988. METHODS: A county-based typology of the urban-rural continuum was employed to examine trends in the supply of nonfederal primary care physicians, specialist physicians, and osteopaths. RESULTS: All urban and rural areas gained physicians during the late 1970s and 1980s. The supply of physicians increased most rapidly in metropolitan counties. Within nonmetropolitan areas, urbanized remote counties became more prominent centers of the physician supply. Osteopaths were more likely to locate in the most rural areas than allopaths. The physician supply in all areas also became more specialized over time. CONCLUSIONS: The rapid growth of the US physician supply was associated with the spread of more practitioners into all parts of the country. However, the supply of physicians increased most rapidly in urban areas, widening urban-rural differences in the availability of physicians.

The impact of class, education, and health care on infant mortality in a developing society: the case of rural Thailand.

Demographic and social factors affecting infant mortality in rural northern Thailand are examined using log-linear modified multiple regression models and data drawn from a representative sample of married couples in Chiang Mai and Chiang Rai provinces. Demographic factors do not account for the effects of variations in parental ability or willingness to provide adequate infant care. The final model estimated incorporated both these social dimensions of child care. Parental ability, measured by father's social class, mother's health information, and local community development levels, continued to have significant independent effects upon infant survival. Parental willingness, measured by parent's beliefs about intergenerational wealth transfers, no longer had a significant effect net of other social variables, but infant survival was still affected by whether both parents wanted a birth.

Antecedents to contraceptive innovation: evidence from rural Northern Thailand.

A number of different causal mechanisms have been proposed to explain the onset of fertility declines in populations with previously uncontrolled fertility, but they have never been adequately tested. The present study identifies and tests five antecedents to family limitation practices in a sample of 755 currently married couples resident in rural Northern Thailand. The log-linear multiple regression models estimated indicate that couples in more developed districts, more modern couples, couples in which wives have more equal roles, couples believing that intergenerational wealth transfers favor children rather than their parents, and more wealthy couples, were all significantly more likely to be early adopters of contraception. Local development levels appeared to have the greatest net effects on the timing of adoption of fertility control. In addition, couples in areas where contraceptive services were more readily available were also significantly more likely to be contraceptive innovators, net of these five variables.

Survey updates unionization activities.

Survey conducted in 1976 shows that the 1974 amendments to the National Labor Relations Act have speeded unionization of U.S. hospitals. Marked variations in unionization according to hospital type, size, and location continue. Overall, 23 percent of all hospitals have at least one union contract.
