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.
