I'm really confused by your provision of these links.
As of right now (April 2025) they agree with @ooftownroad's assertion that Tuvalu has fewer people than Nauru.
I understand and appreciate the disclaimer in the quiz description, that the figures are as of April 26, 2022; however looking at historical data from those same pages shows that even as of that date, Tuvalu still had fewer people than Nauru?
