Using Union Army veterans' lifetime socioeconomic and health records, this essay finds a consistent and persistent hierarchy in survival rates and hazard ratios by urban size at and across three stages of life: birth, late adolescence, and death. This urban mortality penalty remains after controlling for variables associated with each individual veteran. The results of our geographical mobility analyses suggest that, with respect to these veterans, the search for an explanation should focus on late adolescence and adulthood as much as on early life. A complete explanation of the penalty requires a project of greater scope.
Keywordsurban mortality penalty; cohort analysis; survival rate; hazard ratio; mobility Although it is widely known that, during the 19th century, life expectancy was substantially lower in cities than in rural areas, the differences in survival rates and proportional hazard ratios across urban sizes and rural environments are less well understood. 1 Further, the longitudinal impact of lifetime mobility on life expectancy during this period rarely has been studied. This essay examines these less explored subjects using historical data from Union Army veterans' lifetime socioeconomic and health records collected by the Center for Population Economics (CPE). In particular, using veterans who survived the Civil War, survival rates and hazard ratios are estimated for different urban size and rural environmental categories at three stages of life: birth, late adolescence, and death. We also exploit the association with the local malaria ecology to differentiate rural areas.Our analyses show a persistent urban mortality penalty for all three stages of life even after controlling for health-related events incurred during the Civil War and those incurred by Contact Information for Corresponding Author (Sok Chul Hong) Mailing Address: School of Economics, Sogang University, Shinsudong, Mapo-gu, Seoul, Korea 121-742, Email: shong@sogang.ac.kr, Telephone: +82-2-705-4705, Fax: +82-2-705-8180.
