Notice that there are many more males than females in the USA for in the age bracket when relationships form. The ratio is 1.07 (.73/.68 = 1.07) for 19 year olds. It's incredibly high and I wonder why that is? Think about the implication: No matter what those 107 guys do there will be only enough girlfriends/wives/lovers for 100 hundred of them. The ratio reverses only after age 45. This might explain the extraordina…

Relationships between people that aren't the same age aren't exactly unheard of, and exclusive monogamy isn't exactly an ironclad rule among humans, so two key assumptions underlying your conclusion seem to be invalid.

Interesting that the population age drops off right at 65 (also the retirement age).

That's a function of the Baby Boomers starting to enter their mid-60s.

I would guess it's rather that the birth rate during the war was rather low, given that a lot of young males were either in Europe and/or killed?

Quite interesting so many of the top countries are Muslim (Bangladesh, Pakistan, big chunks of Nigeria and India). I wonder what will happen in the near future when the Muslim population inevitably dominates over the other groups.

As it gets more educated and gains a higher level of living standard, the muslim population will slow its birth rate. A high birth rate is primarily visible in countries where you HAVE to have kids to survive when you get old.

That's not correct. Population growth increased from the 1930s compared to the 1940s, and accelerated during the war (it was eg twice as high in '45 and '46 as '33). The great depression had a much greater impact on population growth than WW2 did. The only negative modern year being 1918 (combination of WW1 + deep recession post war + flu pandemic). Live births also increased during WW2.

I've seen some statistics (not sure about their validity) stating that around 10% of the population are gay/bisexual, so if this were the case then having 7% more males than females wouldn't necessarily be a problem.

Unless 10% of females are also gay/bisexual, then it all cancels out. Also, gender disparities could affect the gay/bisexual communities just as much as the straight community.

It would be neat to have some kind of public display that shows two scrolling lists. One is a real time list of births in the US. The other, a real time list of US deaths.

The birth and death rates are low enough that most of the time both lists would be changing slow enough that you could easily keep up reading them, but high enough that you could see movement and see that the birth list is growing faster.

The death list would probably be the most interesting, as it would be less steady. You'd occasionally see blocks of deaths all in the same location as accidents and disasters happen.

It is specifically about women getting emancipated.

Nigeria is really an oddity. Wonder why the birthrate is that exponential there.
