Nice quiz, but every source I can find gives California a bigger population than Canada (39.5m to 37.5m on 2019 stats). My guess was about 40 to 36, so it's closer than I thought, but according to various sources I've looked up California has had a larger population that Canada for the last 35 years at least, and certainly has a current population greater than 37m.

OK I think the numbers change since I created this. I've now updated it.

The numbers have changed again, and Canada has the larger population since about 2023. Writing in early 2026.
