Most population surveys include categories for individuals identifying as LGBT. Very few surveys focus on only Lesbian/Gay/Bisexual and most surveys do not specifically include other identities such as pansexual, queer or asexual. In 2014, the Williams Institute reviewed two different studies that included only Lesbian/Gay and Bisexual (omitting Transgender). These two studies, the National Health Interview Survey and the General Social Survey found the L/G/B adult population in the US to be between 2.2% and 3.0%. That's more than the size of Los Angeles and Chicago combined --- the 2nd and 3rd largest cities in the US.
