Population

How to study this deck

Exact population figures are hard to hold in memory, and honestly not that useful on their own. What sticks better is order of magnitude: is this a country in the thousands, millions, or hundreds of millions? Get that right consistently and the precise number becomes much easier to pin down afterward.

It also helps to anchor unfamiliar countries to ones you already know. If you know Poland is around 37 million, a country you're told is "similar in size" becomes much easier to place than a bare number would be.
