Blue Eyes Less Common in U.S. Residents of European Descent. Green and Brown Eyes Dominant Over Blue Eyes
Blue eyes are becoming less common in U.S. residents who identify themselves in census and other records as being of European, non-Hispanic ancestry. This is probably because the blue-eyed trait tends to be recessive or less likely to express when genetic influences of brown or green eyes are present.
Annals of Human Biology reported in November 2002 that the blue-eyed trait among people of European, non-Hispanic descent in the United States declined from about 57% in people born between 1899 to 1905 to about 34% among people born between 1936 and 1951.
