 The festivals of Christmas and Easter are widely celebrated in the country.The 2001 and 2011 censuses did not include on adherence to individual Christian denominations, since they were asked only in the Scottish and Northern Ireland censuses and not in England and Wales.However using the same principle as applied in the 2001 census, a survey carried out in the end of 2008 by Ipsos MORI and based on a scientifically robust sample, found the population of England and Wales to be 47.0% affiliated with the Church of England, which is also the state church, 9.6% with the Roman Catholic Church and 8.7% were other Christians, mainly Free church Protestants and Eastern Orthodox Christians.
