It is noteworthy that in the dating site, users' characteristics are all self-reported. For impression management considerations , users can exaggerate their personal characteristics . For example, a recent research on online self-reported height against objectively measured data in young Australian adults revealed that self-reported height is significantly overestimated by a mean of 1.79 cm for males and 1.29 cm for females . Men lie more than women about their height, which is also found in the online daters of New York City . We note that users seem to have not accurately reported their physical height in the dating site. In the dataset, the average heights of female and male users are cm ( \(\mathit=4.18\) ) and cm ( \(\mathit=4.68\) ), respectively. However, in real world the average heights of adult females and males in China are cm and cm, respectively, which means that female and male users can exaggerate their height by an average of 1.11 cm and 4.08 cm, respectively. After correcting these, we find that real height differences \(10-(4.08-1.11) = 7.03\text< cm>\) for men, and \(12-(4.08-1.11) = 9.03\text< cm>\) for women would be significant. However we also notice that in the dating site, the average ages of male and female users are and years old, respectively, while in the overall adult population in China, the average ages of men and women are and years old respectively according to the population census data. The dating population is younger than the overall adult population, thus is likely taller, and users may not exaggerate their height by quite as much as calculated.
