>> Why are the Hamptons and Martha’s Vineyard so white? <<

You need to do some serious research on the question. Martha’s Vineyard is not all-white, at least not during the high summer season. In fact it is perhaps the favorite vacation spot for wealthy blacks who live in places like NYC and DC.

Correct. And I am sure that there are a number of wealthy minorities who visit National Parks, but it seems that the numbers do not match the numbers that some believe should be there based upon some kind of a statistical model.

Frankly, how would the Park service know how many people of any ethnicity are in a park? I do not recall completing an ethnicity survey when I visit National Parks. Are park rangers now running around asking people about their ethnic background?

Martha’s Vineyard = 3.6% Black .......... I can live with that. (Dukes County Massachusetts)

Actually, Martha's Vineyard has a long tradition of black vacationers, over 100 years. It's somewhat ironic in that MV has a statue that is a tribute to the Confederate soldier.

Lots of (racially mixed) Brazilians live in Martha’s Vineyard doing the schlep work as well.
