While listening to Trevor Noah's podcast one of the topics they were discussing was South Africa. Apparently, the apartheid South African government never included Black South Africans in the census. That was how little regard they had for native South Africans they couldn't even be bothered to count how many fellow humans existed in their country. The new government was required to carry out a census in order to know how many MPs were going to be in parliament. And they were blown away by the count. Until then, it was just a guess.
So South Africans not having birth certificates or any birth records is the least surprising.
