There are still millions of gay couples who don’t self-identify on census forms, but this is a good start:

In Fort Worth, Texas, the number of reported same-sex couples rose from 196 in 1990 to 2,254 in 2006, giving Fort Worth the 22nd highest concentration of gay couples in the United States.

The report by the Williams Institute for Sexual Orientation Law and Public Policy at the UCLA School of Law found that the number of reported U.S. same-sex couples had quadrupled to nearly 780,000 nationwide between 1990 and 2006.

Using U.S. census numbers taken every decade as well as recently released data from the U.S. Census Bureau’s American Community Survey (ACS), it found that by far the fastest growth was in areas associated with conservative politics and values.

The number of self-identified same-sex couples has risen 600 percent in the red-state bastions of Texas, Oklahoma, Arkansas and Louisiana.

The east south central states of Alabama, Kentucky, Mississippi and Tennessee saw a combined increase of over 800 percent while the mountain states of Arizona, Colorado, Idaho, New Mexico, Montana, Utah, Nevada and Idaho had an increase of almost 700 percent over that 16-year period.

In Fort Worth, Texas, the number of reported same-sex couples rose from 196 in 1990 to 2,254 in 2006, giving Fort Worth the 22nd highest concentration of gay couples in the United States.
