Both maps below show Ethiopia highlighted. At 9° Mercator inflates Ethiopia by only about 2%, so the two maps largely agree on it. Watch what the old map does to Eritrea beside it. That contrast is why the new world map matters.
At 9°, Ethiopia 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.

Old maps drew Ethiopia at about 1,129,699 km². The truth is 1,104,300 km², a difference of 2% that school atlases carried for centuries.
