SAN FRANCISCO (AP) --

More than 4,000 same-sex couples obtained marriage licenses in San Francisco before the state Supreme Court shut down the practice, a study released Wednesday shows.

Of the 4,037 same-sex couples who obtained licenses in the city starting Feb. 12, more than 91 percent came from California, according to a nonscientific analysis by County Assessor Mabel Teng's office.

The rest came from 45 other states and eight foreign countries, the analysis shows.

It confirms to us that California benefited the most from the service we provided," said Teng, who personally officiated at the nuptials of more than 300 couples.

The analysis also found that more lesbians tied the knot than gay men: Of the 4,037 licenses issued, 2,311, or 57 percent, were granted to women, authorities concluded by reviewing the first names of the applicants.

Eighty-two of the couples either chose not to go through with their weddings or did not return to City Hall in time to register their licenses, a critical final step, Teng said. That brings the total number of known couples to complete the process to 3,955.

Couples from Washington and Oregon, which each sent 32 couples to San Francisco, were the next most-represented group behind California. Nevada, New York and Florida respectively had 24, 20 and 16.

Couples from Canada, the United Kingdom, the Netherlands, France, Denmark, Germany, Switzerland and Thailand accounted for the 188 licenses requested by residents of foreign nations.

The marriages began after Mayor Gavin Newsom directed his administration to grant licenses to gays and lesbians. The Supreme Court handed down an injunction stopping the practice last Thursday.
