How do they get to that quantity? I assumes is world-wide

[billforsternz]

7000 million people in the world. 30 million seconds in a year. 3000 million seconds in a lifetime. So approx 2 people die a second.

I should have made it clearer that this is just a sanity check. I find the rough approximation 30 million seconds in a year often comes in handy for back of the envelopers like this. 10 seconds thought was all it took to check that 2 people dying every second is at the very least reasonable.

Life expectancy is way below 100 years currently. Even for people born now, it's probably only 100 years in some developed countries.

[billforsternz]

It's very much a back of the envelope calculation, everything is very approximate, 100 years makes for an easier calculation.

[truth_sentinell]

Ok, so where's the part where you get that 2 from?

[billforsternz]

Well 7/3 = 2 (more or less - the whole calculation is very approximate obviously). The basic idea is if you have 100 people (of a broad spectrum of ages) you'd expect about 1 of them to die each year.
