One News Now has this posted news report about the numbers of gay people in the United States. Gary Gates biography can be found here:

SAN FRANCISCO – A California demographer has released a best guess of how many homosexual adults are in the U.S.

Gary Gates puts the figure at 4 million adults, representing 1.7 percent of the 18-and-over population. That’s much lower than the 3 to 5 percent that has been the conventional wisdom in the last two decades, based on other isolated studies. It’s also a fraction of the figure put out by Alfred Kinsey, who said in the 1940s that 10 percent of the men he surveyed were “predominantly homosexual.”

Gates has advised the Census Bureau. He’s a demographer-in-residence at the Williams Institute on Sexual Orientation Law and Public Policy at the University of California, Los Angeles.

He derived his results from five studies that asked subjects about their sexual orientations.
