Moving to current cities may still be what's causing life expectancy to increase, even if moving to cities in the past didn't. Cities weren't held constant.

  Of course! But I'd still guess that it's not some intrinsic property of cities, and that a large part of the difference would be explained by income differentials (or job differences - no chance of getting crushed by a tractor in Times Square).

    If job differences are not intrinsic to cities, what is?

      Density, maybe?
      • icebraining 8y ago
        Yeah, and I'd say those differences in density inevitably cause differences in types of jobs. It's second order, but still intrinsic.
