That’s not even factually true. Turnout in 2024 was 63.7%[1] of the voting age population. You’re just wrong.

Huh, I must have inverted that number in my head. Thanks!

If you include people not allowed to vote (e.g under 18) it is below 50%

What do you think "voting age" means? The first sentence on the linked page is "The overall turnout of eligible voters in the 2024 general election was 63.7%"
