The American public estimates on average that 23% of Americans are gay or lesbian, little changed from Americans' 25% estimate in 2011, and only slightly higher than separate 2002 estimates of the gay and lesbian population. These estimates are many times higher than the 3.8% of the adult population who identified themselves as lesbian, gay, bisexual or transgender in Gallup Daily tracking in the first four months of this year. The stability of these estimates over time contrasts with the major shifts in Americans' attitudes about the morality and legality of gay and lesbian relations in the past two decades. Whereas 38% of Americans said gay and lesbian relations were morally acceptable in 2002, that number has risen to 63% today. And while 35% of Americans favored legalized same-sex marriage in 1999, 60% favor it today.Only 9% of respondents estimated the LGBT population to be under 5%.
