sexual orientation

The demographics of sexual orientation are difficult to establish for a variety of reasons. One of the major reasons for the difference in statistical findings regarding homosexuality and bisexuality has to do with the nature of the research questions. Major research studies on sexual orientation are discussed. Most of the studies listed below rely on self-report data, which poses challenges to researchers inquiring into sensitive subject matter. More importantly, the studies tend to pose two sets of questions. One set examines self-report data of same-sex sexual experiences and attractions while the other set examines self-report data of personal identification as homosexual, lesbian, or bisexual. Fewer research subjects identify as homosexual, lesbian, or bisexual than report having sexual experiences or attraction to a person of the same sex. Several studies of sexual orientation in countries provide comparative perspectives. Tables comparing several U.S. cities' population numbers are also included. However, since many individuals may fail to report outside the heterosexual norm define their sexuality in their own unique terms, it is difficult to fully grasp the size of the LGBT population.
Homophobic settings may mean that some LGBT people may not openly identify as such, and open identification of one's true sexual orientation may depend on the status of LGBT rights in a given location
