Abstract

The construct of sociosexuality or sociosexual orientation describes the extent to which people will have casual, uncommitted sexual relationships. The Sociosexual Orientation Inventory (SOI) has been used to measure sociosexuality in many countries, but not in China. The aims of this study were to explore sociosexuality in a cross-section of the Chinese adult population, to quantify sex differences in sociosexuality, and to examine the sociodemographic correlates and the impact of the high sex ratio. The study consisted of a cross-sectional survey using a self-completion questionnaire. It was administered to adults of reproductive age in three provinces: Zhejiang, Guizhou, and Yunnan. While questionnaires were received from 7,424 participants, total SOI scores could be computed only for the 4,645 (63 %) who completed all seven items of the SOI. The mean score for men and women combined was 21.0, very low compared with most other countries, indicating restricted sociosexuality. The men (n = 2,048) had a mean of 27, showing more restricted sociosexuality than in all other countries where the SOI has been used. Wealth was the strongest independent correlate of high (unrestricted) sociosexuality in men and women. The effect size for the difference between the sexes was moderate (Cohen’s d = .64), and comparable to more developed countries, perhaps reflecting relative gender equality in contemporary China. Despite the very high sex ratio, which is theorized to lead to restricted sexuality, its influence was difficult to determine, since differences in sociosexuality between high and low sex ratio areas within this population were inconsistent.

Share of never married females, China & Europe, ca. 1800

-> By age 20-24 most Chinese females were already married, while the vast majority of European females were still single.

-> By age 30-34, virtually no Chinese females remained single, whereas 30 percent of their Western counterparts were still spinsters.

Abstract

This study reports the differences in intelligence across thirty-one regions of the People's Republic of China. It was found that regional IQs were significantly associated with the percentage of Han in the population (r = .59), GDP per capita (r = .42), the percentage of those with higher education (r = .38, p < .05), and non-significantly with years of education (r = .32).

The results of the multiple regression showed that both the percentage of Han in the region and the GDP per capita were significant predictors of regional IQs, accounting for 39% of the total variance.
