More people in Louisiana oppose allowing gay and lesbian couples to marry than support it.

According to The Louisiana Survey, an annual survey conducted by Louisiana State University's (LSU) Public Policy Research Lab, 42 percent of Louisiana residents support marriage equality, while 51 percent remain opposed. Opposition has dropped roughly 5 percent since 2013, according to the LSU survey.

Fifty-nine percent of adults under 29 years old support it, while people 30 to 49 years old are split, with 47 percent opposed and 44 percent in favor.

A large majority (62%) of Louisiana residents who are 65 years or older remain opposed.

LSU interviewed 980 state residents between January 12 and February 13.

In September, a federal judge upheld Louisiana's ban on gay marriage as constitutional, saying it was “reasonably anchored to the democratic process.” Plaintiffs appealed the ruling to an appeals court, which heard oral arguments in January.
