Well-known countries against every country of sufficient size. An overtaking counts if the country was well behind at the start, ahead in no more than a fifth of the years before it, and it lasts to the latest shared year (at least two or three years in a row). A short dip of up to two years does not end a lead and is named. At most three overtakings per well-known country, and each country in at most one card of a kind.
UN estimates (World Population Prospects 2024). Populations age both because people live longer and because fewer children are born.
