On December 19, 2003 The Dallas Morning News ran an article on the changing religious demographics of Mexico. The article reported, "In the last 10 years, the number of Mexicans who consider themselves Catholics has fallen from 89 percent to about 81 percent. The number who consider themselves Protestants rose from about 4 percent to about 9 percent, according to religion experts at the National Institute of Anthropology. The change is spreading fast. Protestants abound in Oaxaca and Chiapas. There are swelling pockets of Mormons in Durango and Chihuahua; and Pentecostals and Jehovah's Witnesses in Guanajuato, President Vicente Fox's home state, known for its staunch conservative Catholic beliefs."
