More gay couples were married in California in the first three months that same-sex marriages were legal than were married in the first four years it was legal in Massachusetts, according to a new study.

The data, released Monday by UCLA’s Williams Institute, found that an estimated 11,000 same-sex couples were married in California from June 17, when the California Supreme Court began allowing the weddings, to Sept. 17.

As of spring, 10,385 same-sex couples had wed in Massachusetts since the state legalized such unions in May 2004, according to a study by the institute released in July.

Next month, Californians will decide whether gay couples can continue to marry when they vote on Proposition 8, which would amend the state Constitution to define marriage as between only a man and a woman.

Predictably, the two sides in that battle had dramatically different reactions to the study.
