User blog comment:Rdv65/no black death world wide - what the consequence over history/@comment-32656-20131114123914

Black Death killed far more people, and in a far larger area, than you think.

Started in China, and over a decade spread west. Places east of Europe suffered just as much as it did.

Overall, if it does not happen or peters out quickly, the population ratio would stay the same as in otl. Biggest difference would be a mildly larger population - with more hunger - and the social order at that time lasting longer.
