How many fit

"How many Japans fit in Russia" is the most asked question in the subject. Every page here gives two numbers: how many really fit, and how many this map makes it look like. They differ, and not always in the same direction.

Really / As Mercator draws it

An empty cell is a pair where fewer than two fit. "How many X fit in Y" presumes more than one does, so those pairs get no page of their own.

Under Equal Earth or Gall-Peters the two figures are identical - for every pair on this site. An equal-area projection draws in proportion to true area, so the count you can see is the count there is. That is a definition, not a coincidence.
