What is the source of the data in this graphic? I'm uncomfortable that it is not sourced. Qermaq (talk) 01:25, 6 October 2012 (UTC)

Why are some christian denominations left out when they have higher membership than non-christian denominations that are included? Also, the numbers don't appear to be accurate. I'm surprised this is still being used. We need a new one based on an accurate source and consistent formatting. Martinaire (talk) 19:31, 21 January 2014 (EST)
