How Many People are Lesbian, Gay, Bisexual and Transgender? | Williams Institute 
This is a recent study done through Williams Institute at UCLA that draws on recent studies and found that only 3.5% of the total population is gay, lesbian or bisexual. this obviously is a much different statistic than Kinsey's research which stated that 10% of males are exclusivity homosexual.

Here is another psychology study Demographics of the gay and lesbian population in the United States: Evidence from available systematic data sources which was published in 2000, so it may be slightly outdated. This study is particularly interesting because of its statistics on percentage of homosexuals in the military and positive correlation between homosexuality and education level.
