We allow roughly one estimated percentile for every 10 samples in the survey. The tool estimates percentiles using all samples, but we're still careful of heteroscedasticity at the extremes. (And, let's be honest - that's where most of the interest lies.) You can see the report on sample...
Time-inconsistency problems related to top coding in theses data have led many researchers to use the ratio of the 90th and 10th percentiles of these distributions (P90/P10) rather than a more traditional summary measure of inequality. With access to public use and restricted-access internal CPS...
