The Institute for Urban and Environmental Studies, Chinese Academy of Social Sciences (CASS) recently released a report stating that China’s current urban-rural income gap ratio is 3.23:1, which means that China has one of the largest urban-rural income gaps in the world.
The urban-rural disparity in the Midwest provinces is even greater. There, the urban-rural income gap ratio is up to 4:1 or more, which is even higher than the national average.
