Contour 1 means that during the modern Chinese people, typically, men like female a couple of years more youthful than simply her or him and you may ladies favor guys 24 months older than her or him. Although not, all of the years improvement that women undertake try smaller compared to that boys: minimal years female undertake is the fact guys are 11 ages young than her or him plus the glamorösa kinesiska-flickor restrict many years it deal with is the fact guys are 23 ages more than them, because the minimal age people take on is that women can be twenty five age younger than just them together with maximum age they take on try that ladies is 28 years over the age of them. Only if the age improvement distributions are believed, in accordance with past findings regarding a selection of countries and you may religions , we discover that a number of many years that women are ready in order to message try narrower compared to the variety of decades you to definitely men are prepared to message. Men and women choices commonly random; it find potential times having an inferior age distinction than forecast by the random choices, which ultimately shows the fresh new feature from enjoys-notice.

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 \(10-(4.08-1.11) = 7.03\text\) for men, and \(12-(4.08-1.11) = 9.03\text\) 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.
