This note analyzes China's provincial diversity from two perspectives. First, the regional gross domestic products of China's 31 mainland provinces are compared with the national GDP of other countries. This demonstrates that China's most advanced provinces and urban areas have per capita GDP levels comparable to those of Sweden and Singapore. On the other hand, China's least developed provinces have a standard of living similar to those of Sudan and Honduras. The second part of the analysis demonstrates that China's economic diversity is not unique. In fact, European countries exhibit almost the same degree of income diversity as do Chinese provinces.
