Honestly, the Wikipedia article is a bit of a mess. I used the percentage figures, and then calculated the absolute numbers using the current country population.
Just people liking to think in boxes, but cant agree what the box is or in which box something fits.
(@kalbahamut, thousands of years is not correct, it definitely was not after 1 AD...) even one thousand years is more than I see described everywhere, usually about 500 years is given between them. it does depend what requirements you use for civilisation. A writing system, laws, agriculture advanced structures. )
The entire population of suriname does not even reach 600.000 so there is no way it could make it on this list. and if you would take the percantage that is atleast partially from african descend (not just subsaharan) you would ony be at about 200k. The netherlands would be on there before suriname, it has more than 2,5x as many (and panama and guyana are also below that. The same goes for everything in the Caribbean, the total population is lower than the lowest number on this list, so no way they could be on it.)
Mexico and usa are huge, so they only need a tiny % to make the list. It is not a joke at all, it makes perfect sense..
you could also wrap each paragraph in < p> and < /p>
That's how I did this
