Abstract: The existing approaches have two main disadvantages. Some methods depend on middle income demarcation, and some methods can only get partial ordering, not complete ordering. To tackle these two issues, we construct a new index to track variation of middle income population size through integrating M-curve by three different weighting schemes. As a composite index, the new index can be used for historical evaluation and regional comparison of middle income population size, which does not depend on middle income demarcation and can get complete ordering. At last, the index is applied to integrated data of Chinese urban residents. The empirical results show that the population size of middle income group in China decreased sharply from 2001 to 2006, and enlarged from 2006 to 2011. In comparison with other countries, we find that the population size of middle income group of some countries can be ordered as follow: Japan, China, United Kingdom, United States, India.
