That's a proximate (mechanistic) explanation; here's an ultimate (evolutionary) one. Pattern observed first in 1662 http://www-personal.umich.edu/~kruger/Kruger-MFMR_LHT.pdf …pic.twitter.com/lRL4515hDG

I seem to remember that boys tend to be born earlier than girls. This likely makes them more vulnerable.

Tricky issue as the pattern persists through out the entire lifecycle - i.e. men die at higher rates regardless of age group. No one cause.

How is that even possible? If true for young age groups (seems logical), very unlikely for older groups since men are dead b4 they get old

Higher rate != greater number. Related:http://www.npr.org/sections/krulwich/2013/06/17/192670490/why-men-die-younger-than-women-the-guys-are-fragile-thesis …

Based on the article, dying rate of men born pre 1900 is 0 (none left), rate for women is higher since there are some left.

No. It's undefined. You can untag me.

This doesn't account for the sad practice of infant sex selection prior to birth.
