The Evolution of Longevity: Evidence from Canada
NBER Working Paper No. 24929
We find a steep earnings-longevity gradient using fifty years of administrative data from Canada, with men in the top ventile of earnings living eight years (11 percent) longer than those in the bottom ventile. For women, the difference is 3.6 years. Unlike the United States, this longevity gradient in Canada has shifted uniformly through time, with approximately equal gains across the earnings distribution. We compare our results using cross-sectional and cohort-based methods, finding similar trends but a steeper gradient when using cohorts. For middle-aged men, we find a cessation of mortality improvements in recent years, comparable to changes observed in the United States. Changes in income do not explain cross-time or cross-country differences.
