Look again at the annual statistics table. They have the classification of "Korean" and "Puerto Rican". Korean doesn't appear at all in the Federal coding scheme and Puerto Rican is lumped in with Caucasian. Those two categories would have to have separate code numbers in their coding scheme. Isn't that why you code in the first place? Doesn't coding break out the categories you want to study?
"That looks like a 7 to me."
Might be a two.
Puerto Rican was coded as white for Fed stats. According to the Fed manual, Korean was likely coded as “other non-white”. I don’t have the answer for you as to why the Feds did it that way, except that this is for race, not nativity. Spanish, Puerto Ricans, etc. are considered Caucasian.
