I find the top three ratios interesting: there's a tiny skew towards females but a huge skew towards males.
It doesn't show what the green threshold is though. From memory, the natural birth ratio is 49:51 m:f, so the female skew is only about 3% while the male skew is about 20%. Seven times larger.
If I were colouring the map, I don't think I'd have bothered with differentiating purple and green, or perhaps used more graduations.
Just a guess, but I think the difference in a country like Qatar can be explained by the import of labor. They hire a workforce from a different country which tend to be dominantly male in those regions. And we've seen with the football WC how they're developing.
https://seasia.co/infographic/qatar-population-by-nationalities-2024 reckons 20% of the entire population of Qatar are Indian. If that's mostly workforce then yeah. It could easily be the skew.
My guess is that there isn't a country out there that has a cultural preference for women over men, so at best you're going to see fairly close to equal, plus the difference of men dying earlier from things like wars, dangerous jobs, and lifestyle.
Whereas there are many cultures that strongly select for male children, plus some that also bring in high numbers of male workers.
Yep, that's the point I was circling around ;-)
I was wondering if there was a correlation between purple and war. There certainly was in early C20 post world-wars.
A lot of countries / cultures do still have bride prices , i.e. reverse dowry, so there is some economic incentive for women there but probably not enough to commit infanticide or selective abortions that causes some of the lopsided male ratios.
India prohibited doctors from telling parents the sex of their unborn child to combat sex selection.
