Sexual Orientation by Gender

Error bars indicate the upper and lower bounds of the 95% confidence intervals.

* The larger confidence intervals for participants in the "Fluid/Both/Neither" category compared to the "Male" and "Female" categories are mainly due to the substantially smaller number of individuals self-reporting this gender category.
