  • It is, population size has essentially no effect on statistical significance of a sample (other than amplifying it as you start to sample most of the population). 20,000 people is massive and will give you sub 1% confidence ranges. The difficulty is ensuring you have a representative sample (no one does) and correcting for the biases you do have in your sample.

    Do you really think the huge polling industry is unaware of basic statistics and your dividing the sample size by the population would come as a revaltion to them?
