THIS ARTICLE at Vatican Radio gives the statistics for the number of Catholics, priests, schools, educational institutions, etc, throughout the world. These statistics are a couple of years old, from December 31, 2012.
Among the numbers:
1,228,621,000 ( > 1.2 billion) Catholics worldwide. There was an increase of over 15 million.
414,313 priests – Europe and the Americas are losing priests (Europe very quickly, the Americas more slowly), while Africa and Asia are adding them. There was actually a small increase in the number of priests over 2011.
702,529 women religious – There was a drop of over 10,000 from the previous year. The number of women religious is dropping quickly. I know in the United States, women religious are generally very old (with a few younger, traditionally-minded orders), so if that is the trend, worldwide, I’m not surprised.
The article has other other stats as well.
