Abstract: nlarging the size of middle-income group is the proper meaning of promoting common prosperity This paper uses 60% and 200% of the median income of 28 EU countries as the lower and upper cutoffs to define Chinese middleincome group and analyzes its size and growth path from an international perspective The results show that the size of middleincome group in China has grown rapidly，from less than 1% in 2002 to 247% in 2018，and its number is similar to the total number of middleincome group in 28 EU countries and similar to the total population of the United States in that year In the past 20 years，among several major middleincome countries，only the size of middleincome group in China has maintained rapid growth Compared with developed countries，the proportion of middleincome group in China is still low，and it is still in the climbing stage of “GDP per capita” and “the proportion of middleincome group” The birth background beyond personal control，such as Hukou type，parents employment and education level，and place of birth，has a significant impact on a persons probability of being middleincome group In the future，we should pay special attention to those who are born in disadvantaged backgrounds and provide them with smooth channels to enter the middleincome group
