I don't place a whole lot of stock in statistics, but it is interesting to note that of the world's 6.7 billion person population, the Catholic Church's numbers remain stable at about 1.1 billion members (17%) and the number of Catholic priests has increased slightly worldwide to approximately 408,000.
Does that number seem small to anybody? That's one priest per 2,700 of us. Christianity is still the largest religion in the world at about 2.1 billion persons (33%); Catholics make up about 50% of all Christians worldwide.
In 2005, there were 69.1 million Catholics in the United States representing about 23% of the total U.S. population.
