at first that looks like a Mollweide projection, but it isn’t, it’s a slightly distorted one or some other. so it should read ‘this ellipse’ instead. the areas near both poles are appear larger than they are. but yes that’s much people.
I guess it is a Winkel-Tripel projection, a good overall approximation, used in many situations and preferred by the National Geographic Society.
