Los Angeles County is where the most California gays are getting married, according to a recent study.

The Williams Institute at the UCLA School of Law reported that 2,719 gay couples tied the knot in Los Angeles County, edging out San Francisco County's 2,708 same-sex marriages.

Five counties -- Los Angeles, San Francisco, San Diego, Riverside and Alameda -- account for 80 percent of the estimated 11,000 married same-sex couples in all of California.

Researchers at the Williams Institute also published three other studies on the demographics of same-sex couples in California.

Here are some highlights:

- nearly 25 percent of the couples are raising children, totaling 52,000 kids;

- there are 109,000 same-sex couples in California, up from 90,000 in 2000;

- California is home to the largest percentage of same-sex couples; and

- 861,000 lesbian, gay and bisexual adults live in California.
