        Is there any evidence that it reflects different populations? i.e. decadent city living produces less healthy doing more reproducing, rather than environmental factors

        It says only "the pattern is repeated more or less clearly in nearly all regional subsets, which would argue against migration as an explanation."pic.twitter.com/QNVDIrCHfp

        The Malthusian explanation is actually that populations keep growing while there is still food for further people. Since this is assumed to be very fast, they are practically always at maximum size with the *same* minimum for living conditions. Prediction is no change over time.

        All the comments here are garbage. It is simply a 1:1 dietary effect on effective vs potential height, common knowledge in the field of Demography 🙄

        This was my first thought too. With better living standards, survival filters cease to function. Which is why I am rooting for technologically fixing the genetics of people where the genetics are faulty.

        Depends ... this verbiage strongly suggests predisposition to “population pressure”. Were the so called effected in the most populated regions? San Fran doesn’t look like Atlanta... Boston doesn’t = Seattle... and there’s a LOT more than population dynamics going on there ...

        Conclude that city living has always been unhealthy; though when the aqueducts failed and infrastructure collapsed, hygiene failure probably contributed to increased mortality. Weird equilibrium between unhealthy/long life and "healthy"/shorter life?

        Though reduced density and collapsed trade nets would certainly help with reducing epidemic transmission rates...
