You cannot buy years of life directly. But the housing market bundles them with the address: ZIP codes whose residents live one year longer cost, on average, about a third more — and the local exchange rate runs from $18,000 a year in Cincinnati to $141,000 in San Francisco.
Economists call it hedonic pricing: a house's price is the sum of what the market will pay for each thing bundled into it — the bedrooms, the school district, the commute. This story prices the grimmest amenity in the bundle. Join every ZIP code's median home value to the life expectancy of the people living there, and the market reveals what it has known all along: longevity is capitalized into real estate.
Each dot is a ZIP code. The relationship is logarithmic — each doubling of home value buys roughly the same 2.2 extra years — which is why the same year of life costs so much more where housing is already expensive. From the cheapest twentieth of ZIPs to the priciest, average life expectancy climbs six years.
Compare the full distributions for the cheapest fifth of America's ZIP codes and the priciest fifth. These are not overlapping curves with different averages — they are substantially different populations. The cheapest quintile's best outcomes roughly match the priciest quintile's worst.
Within each metro, regress life expectancy on log home value and invert the slope at the metro's median price: how many housing dollars separate ZIP codes one year of life apart? The ordering is not just a cost-of-living artifact. In the Midwest's affordable metros the gradient is brutally steep — Cleveland's correlation between price and longevity is 0.91, the tightest in the country — so a year changes hands cheaply. In coastal metros, expensive housing is everywhere, including in neighborhoods that are not healthy, so each year costs six figures.
No one writes "life expectancy" into a listing. The market prices safety, air, parks, hospitals, walkability, and neighbors — and those amenities are the same machinery that produces longevity. Nor does buying into an expensive ZIP code purchase its life expectancy: these are the lifespans of current residents, who differ from movers in income, health, and a hundred unmeasured ways. The honest reading is not "pay $141,000, live a year longer." It is starker: the price system has already discovered the longevity map and made it a entry fee. In Cleveland, a year of neighborhood life expectancy trades at the price of a used car. What story № 1 measured in subway stops, the market measures in mortgages.
