Also !nooticers, I want you to nootice specifically the female excess of seniors citizens. It is commonly stated that foids live more than moids, however in the pre-1950 pyramid there's no gender gap. Post 1950 there's an excess mortality among men leading to a female excess among the 50+ which becomes more pronounced by the 1970s. What happened?

Bonus for the chuds who want the racial composition pyramid :marseyrepostsign: from 1900-2020
