Second question - looking at ETHN_PCTS...I get that the higher a number means that ethnicity is used more often, but what are those numbers relative to?
In a lot of cases, the ETHN_PCT numbers add up to 100 which makes sense. But the numbers for the US add up to 3256, and Puerto Rico only has one with a value of 90. Can somebody explain what these numbers actually mean?
