This is a nice observation that triggers a question from my side. Normally polls, for example voting polls, need a sample size of ~3000 random people to represent the voting decisions of millions.

Wouldn't it be similar in this case? We are less than 10'000 so a sample of ~100 people may be a good approximation of all of them?

Note that I am asking, I never dived in the mathematics of sample sizes (if you have directions to follow, please share!)
