While the stats are accurate, the self selection may not represent the pop at large.
Of course this only paints part of the picture, since it sliced and diced the data differently. Ideally you’d have much more comprehensive statistics about people in relationships, and the statistics wouldn’t just be % of intermarriage, but all marriages. However you should be able to extrapolate, since all marriages = interracial + interracial marriages. So if asian females have higher rates of intermarriage and males don’t, then there presumably are a surplus of unmarried asian males (and black females for that matter).
