A poll released Thursday found record high support for gay marriage among California voters.

Sixty-one percent of the 834 people surveyed by the Field Poll said they support marriage equality, while 32 percent remain opposed.

Among people 39 and younger, 78 percent support such unions. A majority (56%) of middle-aged respondents also are in support.

The Field Poll's 1977 survey, the first to ask about the issue, found a large majority (59%) opposed to allowing gay couples to marry and only 28 percent approved.

The survey results arrive a month before the U.S. Supreme Court is scheduled to hear oral arguments in Perry v. Hollingsworth. The case challenges the constitutionality of Proposition 8, the 2008 voter-approved constitutional amendment which put an end to the weddings of gay couples taking place in the state after the California Supreme Court struck down the state's law excluding gay couples from marriage.

More than 18,000 gay and lesbian couples married before Proposition 8 took effect.

Efforts to repeal the amendment have failed to gain sufficient support from major gay rights groups in the state. Most have said they are waiting to see how the Supreme Court rules before committing to an expensive ballot initiative.
