I've always wanted to make a hex map for my home country Nigeria because who doesn't love a hex map? So here's an interesting map for y'all. This map shows the polygyny rate by state in Nigeria. Polygyny, the marriage of a man with several women, is the most widespread and acceptable type of polygamy worldwide. Polygynous marriages based on customary law are legally accepted in Nigeria for Muslims. This is why polygyny is more widespread in Nigeria's north, where the majority of Muslims live.
