I'm not going to speculate about this one, but this confirms American Community Survey data found in years past:
The changes may seem surprising for a city where churches that have long condemned homosexuality remain a powerful force. But as demographers sift through recent data releases from the Census Bureau, they have found that Jacksonville is home to one of the biggest populations of gay parents in the country.
In addition, the data show, child rearing among same-sex couples is more common in the South than in any other region of the country, according to Gary Gates, a demographer at the University of California, Los Angeles. Gay couples in Southern states like Arkansas, Louisiana, Mississippi and Texas are more likely to be raising children than their counterparts on the West Coast, in New York and in New England.[...]
Black or Latino gay couples are twice as likely as whites to be raising children, according to Mr. Gates, who used data from a Census Bureau sampling known as the American Community Survey. They are also more likely than their white counterparts to be struggling economically.
