A new survey conducted by public opinion research firm Gallup has found that 3.4 percent of Americans identify as gay, lesbian, bisexual or transgender.

The poll, conducted between June 1 and Sept. 30, 2012, asked participants “Do you, personally, identify as lesbian, gay, bisexual or transgender?” More than 121,000 responses were collected, according to Gallup.

Previous surveys have shown the number of LGBT Americans could be as high as 4 percent. Gallup says this most recent study is the largest such study on record.

Other findings show that women are more likely to be LGBT than men, but only by a slight margin: 3.6 percent of women surveyed identified as LGBT, while only 3.3 percent of men said the same.

Younger adults (18 to 29) were more than three times as likely to identify as LGBT than seniors aged 65 or older. Nearly 9 percent of young women surveyed identified as LGBT.

Not surprisingly, the South was behind other regions in the country with those who identified as LGBT. Only 3.2 percent of those surveyed in the south identified as LGBT, while those living in the west and eastern regions of the country were 3.6 percent and 3.7 percent respectively.

Gallup's analysis found that many stereotypes about the LGBT population should be challenged:

This initial analysis reveals new insights into the composition of the LGBT community in the U.S. In particular, the findings challenge both media and cultural stereotypes to reveal that the LGBT population is in a number of ways not that different from the broader U.S. population.
