That population increase statistic was a little shocking (+2.7B in our lifetimes). I suppose I knew it already, but it hadn’t clicked how crazy that is.

I just realized we're less than 1 year away from reaching 8 billion people on Earth. A bit scary.

It would be much scarier if it was decreasing or staying flat, though.

Why?

I don't doubt you, I just don't know anything about this. My first guess is that economically it would be potentially catastrophic.

It’s hard to give an exact answer without more granular data than I can find given that it changes year to year. However, very approximately:

0.5 percentage points (pp) infant deaths (birth defects, delivery complications, neonatal death, etc.) 6.5 pp deaths under 5 from infectious disease (primarily pneumonia and diarrheal diseases) 0.5 pp injuries (fairly evenly split among homicide, suicide, drowning, road accidents, other accidents, but with the last two taking somewhat larger shares)

Over the next decades most in your cohort will die from heart disease, stroke, or COPD.

I feel slightly threatened ;)

That’s a great looking life you’ve got there, full of promise… it’d be a shame if anything happened to it.

Me too, I was 1984 and it was the same percentage.

Same for 1983. And 1982.

Given it's 9% for my cohort (1980), I'd say childhood mortality is mostly focussed on the first year.
