=== Censuses ===
Questions of religion are "marginal" in censuses, usually optional, and are left out of most censuses in most countries.<ref name="Thor">{{cite journal |last1=Thorvaldsen |first1=Gunnar |title=Religion in the Census |journal=Social Science History |date=2014 |volume=38 |issue=1–2 |pages=203–220 |doi=10.1017/ssh.2015.16}}</ref> Despite attempts to standardize wording, census phrasing of the religion question have not been consistent over time or from country to country, with responders understanding them in 3 different ways.<ref name="Thor" /> Censuses aim to enumerate religious communities, not religious faith, and "as long as the censuses in more than half of the world do not ask about religion it will not be possible to tell even within the closest million the size of the different religious communities globally."<ref name="Thor" /> Due to the complexity of measuring religious identity, censuses sometimes also overestimate groups; this was the case for Christians in Britain, as typically one person fills out the census one behalf of a household, as distinguished from surveys which ask individual adults.<ref>{{cite journal |last1=Voas |first1=David |last2=Bruce |first2=Steve |title=Research note: The 2001 census and christian identification in Britain |journal=Journal of Contemporary Religion |date=January 2004 |volume=19 |issue=1 |pages=23–28 |doi=10.1080/1353790032000165087 |url=https://www.tandfonline.com/doi/abs/10.1080/1353790032000165087 |language=en |issn=1353-7903|url-access=subscription }}</ref>
