Religions Census

Since the 1950 's, the US Census Bureau did not question the question about American religion, but in the previous century the federal government gathered some data. During the Civil War, federal and assistant marshals served as investigators and gathered data on religious leaders and priests, the number of churches, religious beliefs, and the number of seats and property. According to the 2010 Central Analysis Journal, the Census Bureau allows only voluntary questions about religious activities in certain censuses and household surveys (USA).

Religion was a census variable in Indonesian censuses and various internal investigations in 1961, 1971, 1980, 1990, and 2010. Because the division was perceived, census data on religion in 1961 has not been released. In 1971, three groups of Christians were recorded: Catholics, Protestants, others. United Nations Demographics Yearbook 1979 lists only the statistics of all Christians. In the 2000 census, only Catholics and Protestants were categorized.

In the 1960s and 1970s, the Census Bureau once again considered several requirements that individuals and organizations need to include religious issues in the census of 10 years. However, the Census Bureau believes that this issue "does affect the separation of traditional churches and states", so it is not included in the 1970 census. By the mid - 1970 's, the problem was reproduced and discussed. A public meeting on Census Bureau planning was held in cities nationwide. Supporters, including religious issues, emphasized the importance of religion in American living and pointed out that religious-related issues include censorship in other countries such as Canada and Australia.

Irish census data does not provide classification of religions other than major Christian sects and other major religions of the world. A total of 22,497 people suggested other religious beliefs at the 2006 census and in 2009 there were around 2,000 to 3,000 infidels in Ireland. There are many pagan groups in Ireland - mainly magic and druid - none officially recognized by the government. Pagans in Ireland pay close attention to regional and language problems
