VATICAN CITY, Feb. 5 (UPI) -- Within only a year, the Roman Catholic Church has grown by 10 million to 1.07 billion worldwide, according to the Vatican's latest yearbook.
Catholics make up 17.2 percent of the world's population, says the Pontifical Yearbook for 2002, which has just been released. This makes it by far the largest Christian denomination internationally.
With 554 million faithful, Pentecostals are the second largest Christian group worldwide, reports religion researcher David B. Barrett of Virginia Beach, Va.
They are followed by the Eastern Orthodox (218 million), Anglicans (83 million), Reformed (75 million), Methodists (70 million), Lutherans (65 million), Baptists (53) and Adventists (13 million).
