A new U.S. Treasury Department report based on federal tax return data indicates that the rate of gay marriage in Evanston is among the highest in the nation.
While not as high as the 4.32 percent of all marriages level reported in San Francisco, Evanston's 1.1 percent level makes it one of the highest in the country — slightly over the 1.0 percent level in Chicago, and roughly three times the state and national averages.
Other areas with high gay marriage rates include Washington, D.C., at 3.66 percent, New York City at 3 percent and Boston, Mass., at 1.91 percent. The nearest community with a rate close to Evanston's is Madison, Wis., where same-sex unions account for 1.15 percent of all joint tax filings.
The report compares same sex marriage data from 2013 and 2014, the most recent available following the Supreme Court decision allowing same-sex couples to file joint tax returns.
A New York Times report on the study provides an interactive map showing same-sex marriage levels by three-digit ZIP codes.
