| | Who knows the number of Christians?
The same pollsters that make such lousy predictions of elections seem to love to tell us that the Christian population is declining. I encourage being dubious of their numbers, especially when they claim worldwide knowledge.
Do you really think anyone knows the number of Christians in China, or Russia, or most countries?
I think the most important number is the number of people attending your church, and that's the number you should be praying and helping to improve. Remember also the homebound as well as those who have moved away, because they are members in Spirit.
I encourage members to seek numbers from their churches, and report them here. The following Catholic numbers are from Cara.georgetown.edu:
parish reports: 1990,55.7mil; 2000,59.9; 2010,65.6; 2017,68.5
survey results: 1990,62.4; 2000,71.7; 2010,74.6; 2017,74.3
