Abstract:
"This paper examines the adult-mortality transition in Costa Rica and its determinants. The risk of dying declined by 80% for young adults and by 40% for old adults from 1920 to 1990. The fastest decline took place in the 1950s for young-adult ages and in the late 1980s for old-adult ages.... By 1990, about 40% of Costa Rican deaths are caused by accidents and violence at young-adult ages and by cardiovascular diseases at old ages. Infectious and nutritional-related conditions (especially respiratory tuberculosis and malaria) account for three-fourths of the adult-mortality decline between 1951 and 1971, but only for 30% since that year on."
