In one of my previous articles I briefly mentioned about the global distribution of IQ level by country. Aside from European-whites, Eastern Asians also have exceptionally high IQ level on average.
The Chinese, with a population of 1.3 billion (91% Han Chinese), have a very high IQ average of 105. But little is known for the IQ level in different regions of China, whereas geographically and demographically it is simply too vast to ignore the regional discrepancy within the country itself. After an amateur scavenger hunt on the internet I actually did find some Chinese source about the IQ geography in China.
The data I found came from a website that offers self IQ tests for the Chinese netizens. Information such as age, geographical location were collected for the correlation purpose for the test result. The original statistics could be found here (in Chinese). I have constructed a series of simple diagrams for the IQ level by province in China (with the amount of participants in each province), as follows:
There are 63,636 participants who took the IQ test on this website from all 31 provinces in mainland China. The mean IQ level of all participants is 106. This is more or less close to the figure given in Lynn’s IQ and Wealth of Nations. Considering the skewed effect of having more participants from regions with apparently higher IQ (e.g. Beijing, Shanghai, etc.), the average IQ level from the test might be slightly deviated from the actual average IQ level of China. Nevertheless, it could still give us a general idea of the IQ geography in China.
There’s a lot to be drawn from the IQ level by province data in China. From a simple glimpse of this IQ map of China, it is evident that the highest IQ level concentrates in the Central Eastern coast of China (around Shanghai, traditionally called Jiangnan). This region in China is famous for its beautiful nature, nature resources, and most importantly, talented intellectuals and traders. This region also happens to be the locomotive of China’s soaring economy. Interestingly, 5 out of 8 Chinese Nobel prize winners (except for the lame peace award which literally means nothing but a leftist scam) come from this particular region of China.
Besides Jiangnan region, high IQ level was also observed in economic strongholds such as Beijing and Guangdong. Those regions surely attracts more smart people than elsewhere in China.
The exceptionally high IQ level of Gansu, a northwestern underdeveloped province in China, could result from the skewed sampling in the study (merely 612 participants claimed to be from Gansu). It is possible that those participants might misrepresent the actual IQ level in Gansu (given that most of Gansu still struggles from poverty and environmental hardship).
Central-south China has a relatively high IQ level (including Hunan, the province I am from). This region is known for its fertile land and mild climate. This region is considered the core of China proper with extensive historical sedimentation that nurtures the rise of Chinese civilization. (off the topic: Hunan is know for its ferocious political and military figures in modern China!).
The relatively low IQ level regions in China largely overlap with the geographical region that has high minority populations with harsh geographical and climatic environment. It is unclear, however, about the role of ethnicity profiles in this observation. This study contains no data about the ethnicity of the participants. Hence, it is inconclusive to say that minorities have a lower IQ tendency compared to Han Chinese in this study, though it is probably the case in reality (from other parameters to judge high IQ level such as level of agricultural productivity, civilization etc).
Overall, this data at least shows us a general impression on the IQ level in different provinces of China. Hopefully there are more studies available for such topic in the future.
