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.

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.

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.
