Religion in China
There has been much speculation by some Western authors about the number of Christians in China. Chris White, in a 2017 work for the Max Planck Institute for the Study of Religious and Ethnic Diversity of the Max Planck Society, criticises the data and narratives put forward by these authors. He notices that these authors work in the wake of a "Western evangelical bias" reflected in the coverage carried forward by popular media, especially in the United States, which rely upon a "considerable romanticisation" of Chinese Christians. Their data are mostly ungrounded or manipulated through undue interpretations, as "survey results do not support the authors' assertions".Besides the surveys based on fieldwork, estimates using projections have been published by the Pew Research Center as part of its study of the "Global Religious Landscape" in 2010. This study estimated 21.9% of the population of China believed in folk religions, 18.2% were Buddhists, 5.1% were Christians, 1.8% were Muslims, 0.8% believed in other religions, while unaffiliated people constituted 52.2% of the population. According to the surveys by Phil Zuckerman published on Adherents.com, 59% of the Chinese population was not religious in 1993, and in 2005 between 8% and 14% was atheist (from over 100 to 180 million). A survey held in 2012 by WIN/GIA found that in China the atheists comprise 47% of the population.
