Abstract: Objective To study children's intelligence after universal salt iodization (USI) had been implemented for 10 years in China. Methods: The children of 8 to 10 years were sampled by population proportion sampling method. The samples were divided into groups according to the province, age, sex, urine iodine. Intelligence quotient (IQ) values were measured by the combined Raven's Test in China (CRT-C2). Results The mean IQ of children was 103.4

It's not really the "average", because every province has about the same sample size.
For example Zhejiang has 54 million people, and Tibet has 3 million, but they have about the same sample size in the data. So the result is skewed to Tibet.

1200 is a large sample size, which is enough for every province. 103.4 is the weighted average.
Most importantly, it's the ONLY official data as a China's IQ research.

I didn't read the original article so I don't know if it is a weighted average or simple average.

I don't know how much I trust data from Chinese trying to study the IQ of other Chinese. Which IQ test did they use? Did they selectively test children that were only in certain schools that may not reflect the average? If the test isn't a common IQ test, what did they do to normalize the scores to 100? I simply don't buy these numbers. The average IQ of Hong Kong is the highest of any country or territory on earth. The average IQ is 107. I simply don't believe that Shanghai is 8 points higher than Hong Kong. That's like saying the average citizen of Shanghai is as intelligent or more than the college educated people of Hong Kong.

First of all, the IQ test is called ''combined Raven's Test in China (CRT-C2)''.
And the IQ result for every province is the weighted average of the population of every city in that province. And they both test children in urban and rural area of every city. The article mentioned very clearly in first 2 pages (if you can read Chinese) that they use probability proportional to size ('PPS') sampling method for every province, every city(市), every county(县), and every district(区) of each city. And using Simple Random Sampling (SRS) method to choose random primary schools in every disrict/county, then in every school been chosen, they randomly choose 40 8-10 years old children to conduct the IQ test.
When the scales are different, the results will be different. There are usually 2 types of IQ tests :Raven's Progressive Matrices(Nonverbal, always been used to testing children); and Wechsler Adult Intelligence Scale.

According the stereotype in China, people in East China are indeed smart, so are those in provinces near the Yangtze River. Hong Kong is in the deep south of China, where people are not stereotypically very smart. But Hong Kong is a major city attracting people from other places, and it is supposed to be above average in that region.

This set of data actually reflects the stereotype in China well.

Shanghai has higher PISA2012(Program for International Student Assessment in 2012) scores than Hong kong.
China IQ map by provinces - 8-10 years old children have average IQ 103.4 in 2005-pisa-2012.jpg

Zhejiang Province's PISA2012 scores posted online by Zhejiang's Education Bureau's website link
Math: 623 (Shanghai 613), 599 on PISA2009
Reading: 570 (Shanghai 570), 525 on PISA2009
Science: 582 (Shanghai 580), 567 on PISA2009

According to OECD PISA Programme:

1. 80% of the students who took the test were from rural areas of Zhejiang on both PISA2009 and PISA2012
2. All top schools didn't participate in the PISA test.

So most smart students in Zhejiang didn't take PISA2012 test .

Zhejiang Province: population of 54 million(native: 47 million). Urbanization rate: 62%.
