Does anyone else really dislike those country or birth-year drop-down list on websites?
I've heard anecdotally from database admins that way too many people were born in 1900 and come from Afghanistan.
Does anyone know a public dataset that shows some sort of artificial distribution due to the user interface? (It doesn't need to be Afghanistan and 1900, that's just a fun example.)
UPDATE: Like @Joe mentioned, I'd also be interested in a demographic dataset that is skewed because of spiders/bots AND the random crap in text fields.
