The New York Times reports: When the District of Columbia is compared with the 50 states, it has the highest percentage of adults who identify as LGBT, according to Gallup. At 10%, that is double the percentage in the state that ranks No. 2, Hawaii, and nearly triple the overall national average of 3.5%. The numbers are based on Census Bureau figures. The Census Bureau looked at where the highest percentage of same-sex couple households were and also found that the District of Columbia ranked far higher than the 50 states, with 4 percent. The national average is just under 1 percent.
