About the Australian Sex Survey

Queensland Behavioural Economics Group (QuBE)
, a high performance research team of The Queensland University of Technology has partnered with Australia’s largest online dating group Giga Pty Ltd, The Eros Association, Australian Sex Party & Max Black, to explore the role that personality, emotion, co-operation, resources and attractiveness play for different sexualities, when they search for a potential mate on the internet. 

“Understanding human behaviour in large scale decisions such as choosing a partner, is incredibly important for all social sciences, and is a currently under funded and under researched field. Independent academic research studies such as this one help to inform policy makers and wider society across a range of vitally important areas, for example; gender equity, marriage equality, income inequality, reproductive health and medicine, mental health, social psychology and education, but to name a few.” -  Stephen Whyte, QuBE researcher & project lead

Study No. 1

Man, Woman, “Other”: Factors Associated with Nonbinary Gender Identification


Using a unique dataset of 7479 respondents to the online Australian Sex Survey (July–September 2016), we explored factors relevant for individuals who self-identify as one of the many possible nonbinary gender options (i.e., not man or woman). Our results identified significant sex differences in such factors; in particular, a positive association between female height, higher educational levels, and greater same-sex attraction (female-female) versus a negative effect of lower income levels and more offspring. With respect to sex similarities, older males and females, heterosexuals, those with lower educational levels, and those living outside capital cities were all more likely to identify as the historically dichotomous gender options. These factors associated with nonbinary gender identification were also more multifaceted for females than for males, although our interaction terms demonstrated that younger females (relative to younger males) and nonheterosexuals (relative to heterosexuals) were more likely to identify as nonbinary. These effects were reversed, however, in the older cohort. Because gender can have such significant lifetime impacts for both the individual and society as a whole, our findings strongly suggest the need for further research into factors that impact gender diversity.
