In attempting to ascertain various impacts on labor market outcomes using categories
such as gender, race, ethnicity, and physical ability, a void exists with respect
to sexual orientation. Whereas heterosexism and homophobia can explain some of the
reasons for the void, the inability to collect data randomly about homosexuals' experiences
in the labor market nullifies the basic tenet of all scientific research-random samples.
A unique approach is presented which looks at income data for nonrelatives of the
same sex, ages 45 to 64, living together in Canada, as a first attempt at comparing
same-sex and opposite-sex genders, and is used to demonstrate the contribution of
recognizing sexual orientation to economic questions. Other examples based on well-known
debates about female labor participation and gender wage gaps are presented to evaluate
the usefulness of studying economics recognizing sexual orientation. The need for
such study is acknowledged as a measure of the inclusiveness of the economics discipline.
