Original Note:
NNN, a quick lesson in statistics: a sample of 1000 is large enough to provide statistically valid results. using Wald's method, one can easily calculate that a sample of 385 is already enough for accurate predictions within a 5% confidence interval https://en.wikipedia.org/wiki/Sample_size_determination#Estimation_of_a_proportion
