It's interesting to note that for a billion people this number changes to a whopping ... 385. Doesn't change much.
I was curious, with 22 sample size (assuming unbiased sample, yada yada), while estimating the proportion of people satisfying a criteria, the margin of error is 22%.
While bad, if done properly, it may still be insightful.

- ethan_smith 1y agoSample size requirements are primarily determined by desired confidence level and margin of error rather than population size, which explains why the required sample barely changes between 1,000 and 1 billion people.
