@UncleIroh I suspect two factors are at play for the many of these numbers. A lower number indicates a lower life expectancy, though also a higher birth rate. A higher number is the inverse with a higher life expectancy and a lower birth rate. May not line up perfectly, but I know it tracks for the extremes of the data.

@UncleIroh

It's a map of the expected lifespan.
Those in green die young. And have many babies. And are dependent on the day of the world to feed them.

Seems like a problem that would solve itself very fast on it's own.
