of whom 30 million Protestants and 3 million Catholics. 2011: a survey conducted by the Baylor's Empirical Study of Values in China (ESVC) found 2.5% (~30 to 40 million) of the population of China self-identifying as Christian. 2012: a survey conducted by the China Family Panel Studies (CFPS) institute, found Christians forming 2.4% of the population of Han China, or between 30 and 40 million people in absolute numbers. Of these, 1.9% were Protestants and 0.4% were Catholics. Surveys on religion in China conducted in the years 2006, 2008, 2010 and 2011 by the Chinese General Social Survey (CGSS) of the Renmin University found that people self-identifying as Christians were, respectively for each year, 2.1%, 2.2%, 2.1% and 2.6% of the total population.

In Wenzhou, a city of Zhejiang, about one million people (approximately 11%) are Christians, the highest concentration in one city. The Protestant population consists predominantly of illiterate or semi-illiterate people, elderly people and women. These characteristics are confirmed by the findings of the Yu Tao survey of 2008, which also found that Protestantism has the lowest proportion of believers who are at the same time members of the CCP in comparison to other religions, and by the China Family Panel Studies' survey of 2012.
