“The Evolution of Longevity: Evidence from Canada” “The Evolution of Longevity: Evidence from Canada” is an in-depth economic study that examines how life expectancy has changed across different income levels in Canada over the past fifty years. Using exceptionally large and detailed administrative data from the Canada Pension Plan—covering more than 11 million Canadians born between 1916 and 1955—the authors investigate the connection between lifetime earnings and how long people live after age 50. The study provides one of the most comprehensive long-term analyses of the income-longevity relationship ever conducted in Canada.
⭐ Core Findings
1. Canada Has a Strong Earnings–Longevity Gradient
There is a clear pattern: Canadians with higher lifetime earnings live longer.
Men in the top 5% of earners live 8 years longer after age 50 than men in the bottom 5%—about an 11% difference in total lifespan.
For women, the top–bottom gap is 3.6 years.
This shows that socioeconomic status is strongly tied to life expectancy in Canada.
2. Unlike the U.S., Canada’s Longevity Gains Are Uniform Across Income Levels
A major discovery:
In the United States, life expectancy improvements have been concentrated among the wealthy, causing income-based survival gaps to widen.
In Canada, all groups—from lowest earners to highest—have experienced similar improvements in longevity over time.
This uniform shift indicates a more equal distribution of health gains across society.
3. Middle-Aged Male Survival Has Recently Stalled
For Canadian men born in the early 1950s:
Survival rates between ages 50 and 60 have stopped improving, echoing—but not matching—the “deaths of despair” pattern seen in the U.S.
Though Canada does not show a mortality reversal, the stagnation signals emerging challenges.
4. Cohort-Based Analysis Reveals a Steeper True Gradient
The authors compare two methods:
Cohort-based (real lifetime data)
Cross-sectional (data from single calendar years, like Chetty et al. 2016 in the U.S.)
They find that cohort-based measures show a significantly steeper longevity gap. This means many studies may underestimate the true inequality in life expectancy.
5. Differences in Earnings Distributions Do Not Explain the Patterns
The study tests whether:
different income levels,
rising top incomes, or
shifts in the earnings distribution
could explain Canada–U.S. differences.
Result:
Earnings differences are not the main driver. Factors such as social safety nets, healthcare systems, and long-term life stress are more likely explanations.
⭐ Why Canada and the U.S. Differ
The paper explores three possible explanations:
Health Insurance
Probably not the main factor, because Canadian universal coverage arrived long after early-life conditions formed.
Education & Health Information
May contribute, but differences are not strong enough to explain divergent trends.
Long-term Economic Stress and Social Hardship
Considered a stronger candidate:
Decades of stress, inequality, and insecurity may wear down health differently in the two countries.
⭐ Overall Conclusion
Canada exhibits a strong but stable earnings-longevity gradient, where rich people live longer but all groups have seen meaningful improvements. This sharply contrasts with the United States, where life expectancy has improved mostly for the wealthy, widening inequality. The Canadian pattern suggests that broad-based social policies and less extreme economic inequality may have helped all earners benefit from longer, healthier lives.... |
