> I drew a woman born in 715 CE in the Yangtze Basin. It claims that 96% of women were married, the average age of marriage was 18, and 44% of women died before age 15. Clearly these facts can't all be true simultaneously.

Yeah, I got: You have drawn a girl, born in the Yangtze Basin in 1295 CE.

Typical age at marriage: 18 Ever married (of adults): 96% Children per woman: 6.5

Life expectancy at birth: 28 yrs Died before age 5: 39% Died before age 15: 44%

Very similar to your "random" draw, and the facts are suspect. There was a link to the source, but it's behind a paywall.
