That is literally what the article describes, though, in Papua New Guinea. And it describes why states in Nigeria have such a strong incentive to fake their population numbers, that it's impossible to achieve an accurate national total.
I do think the headline exaggerates, I doubt "a lot" are fake, but some do seem to be.
No it doesn't. It says the UN came up with a different estimate, which the UN wound up not adopting. There is no evidence that the UN estimate actually used better methods.

I am strictly arguing against "a lot" being fake, and specifically that an isolated example is not evidence of "a lot."
