Clarification-perhaps I overlooked it, but I wasn't sure which category in that frequency ethnicity chart that Black people from the United Kingdom who are not from Africa, or India and are from the UK for generations or are from the Caribbean or the Americas
although I have heard that some people consider the Caribbeans part of the Americas}.

I don't recall that there was an "Other" category. But if that the one Other category is the one that all these people-including people who are mixed African plus some other race[s]-are supposed to use, then the results for Others wouldn't seem to be very percise.

Again, not that this is a big deal. Actually, that's why I curious why it wasn't thought of-if I didn't overlook it. Given the current population of the UK, especially England, {I think}, it seems the inclusion of a Black UKer from the Caribbean category at least would be standard operating procedure.
