Is Latin America Really Catholic?

Acts of Faith, page 244:

...consider that in many Latin American nations where upwards of 90 percent are claimed to be Catholics, there are substantially more full-time Canadian and American evangelical Protestant missionaries than there are diocesan priests (Siewart and Kenyon 1993). In Bolivia, for example, there are 636 missionaries and 221 diocesan priests, or 0.3 priest per missionary. In Honduras, there is 0.2 priest per missionary; in Panama and Guatemala, there is 0.5; in Paraguay, 0.6. For Latin America as a whole, there are only 2.2 diocesan priests per missionary. Keep in mind that the missionary totals do not include more than ten thousand Mormon missionaries. If these are factored in, then for Latin America as a whole , there is only 0.96 diocesan priest per non-Catholic North American missionary. Moreover, if one added in the many thousands of ordained local Protestant clergy, the Catholic clergy would be extremely outnumbered in what has long been depicted as a serenely Catholic world.
