1. Rich people live longer.
2. Richer people's lifespans are growing at a faster rate.
3. The problem is worse for women than for men.
First, let's look at the guys. A rich man (top decile) born in 1940 can expect to live 10 years longer after he turns 55 than a poor man (bottom decile). That longevity gap grew by four years in one generation.
Women live longer than men, overall. But their inequality gap getting worse. A rich woman at 55 can expect to live a decade longer than a poor woman, too. But this gap grew even more between the Silent and early Boomer generations, by six years.
Here's the money chart and it tells a really sad story. In the richest country in the world, the expected lifespan of middle- and lower-income women is actually declining. At every income level, more money means more life.
A few thoughts and implications:
1. Causality: This is your obligatory correlation-is-not-causation caveat. It's intuitive that being rich gives you access to better food, more social connectivity, and higher-quality health care. But this data does not prove that making another $10,000 literally buys you additional months of life. Confounding variables abound. For example, poor people are more likely to be smokers, for a variety of cultural and tax reasons, and smoking kills you faster, no matter what AGI you fill in on your tax forms.
