Christianity in China
Controversy exists regarding the veracity of estimates published by some sources. For example, Gerda Wielander (2013) has claimed that estimates of the number of Christians in China that have been spread by Western media may have been highly inflated. For instance, according to Asia Harvest, a US non-profit organization and "inter-denominational Christian ministry", there were 105 millions Christians in China in 2011. The compiler of these figures, Paul Hattaway, indicates that his figures are his own estimate, based on more than 2,000 published sources such as Internet reports, journals, and books, as well as interviews with house church leaders. The study points out that “owing to the difficulties of conducting such a [study] in China today – not the least of which is the sheer size of the country – there is [in the study’s rough estimation] a margin of error of 20 percent.” Citing one of the aforementioned surveys, Gerda Wielander says that the actual number of Christians is around 30 million. Similarly, missionary researcher Tony Lambert has highlighted that an estimate of "one hundred million Chinese Christians" was already being spread by American Christian media in 1983, and has been further exaggerated, through a chain of misquotations, in the 2000s. Christopher Marsh (2011) too has been critical of these overestimations. On 6 January 2015, David Ferguson published on the "People's Daily" the satirical news "Merry Christmas, 100 million Chinese!" criticising such type of journalism.
