Or have them give the last digit of the age of their oldest living family member.

Due to the distribution of people's age towards the "old" end of the scale, I'd guess that this is more likely to be 0 than 9?

Yeah, I'm curious to look at data, but I think this will be skewed towards lower digits.

What about Benford's Law?

[harryh]

Benford's concerns the first digit, not the last digit.

Except in a distribution that doesn’t go past one digit, of course (no, really, it isn’t that rare to be able to apply Benford’s irl to sequences that don’t go past ten). But, yeah, not applicable in this case.
