mortality across countries, in effect differencing out the country specific SAH response
effects. Third we calculate mortality and SAH “equivalent ages” in the United States.
Fourth, we point out the strong relationship between mortality and a more general
measure of health—the Poterba, Venti, and Wise health index. We draw on two key
data sources--the Human Mortality Database and the National Health Interview Survey,
from which we form a series of SAH by age and year. More information on these data
sources is provided in the Appendix.
