Generic relationships between heterogeneity in population frailty and flattening of aggregate population hazard functions at extreme ages are drawn from classical mathematical results on the limiting behavior of Laplace transforms. In particular, it shows that the population hazard function...

It is easier to discover why people died in the past than how healthy they were during their lives. However, in both Europe and North America, much evidence survives about the health of young males from the medical examination of recruits to the armed forces. The paper discusses the possibility...

Data on human height can provide an index that may measure more accurately changes in the standard of living than the more conventional real wage index. Height data, like those on real wages, are relatively abundant and extend back to the seventeenth century. In a previous paper, we developed...

This paper is a progress report on the usefulness of data on physical height for the analysis of long-ten changes in the level of nutrition and health on economic, social, and demographic behavior. It is based on a set of samples covering the U.S. and several other nations over the years from...
