Both maps below show South Sudan highlighted. At 7° Mercator inflates South Sudan by only about 2%, so the two maps largely agree on it. Watch what the old map does to Sudan beside it. That contrast is why the new world map matters.
At 7°, South Sudan sits in the band the old map drew almost honestly. It is one of the regions Mercator quietly under-represented, and that is exactly what the new Equal Earth map restores.
