Further source info of noted growth ... and I am sure the growth would be much more if the priests scandals would not have occured, and much less if Vatican II did not occur:

"The worldwide Catholic population reached 1.06 billion at the end of 2001, an increase of nearly 1 percent from the previous year.

The number of baptized Catholics in the world had grown from 757 million in 1978 to 1.06 billion at the end of 2001. The greatest growth has been in Africa, where the number of Catholics increased 148 percent since 1978. Significant increases also have occurred in Asia, the Americas and Oceania, while the number of European Catholics has remained about the same over that period."

How many of these are attending Mass? - Not very many.

How many are attending fundamentalist or Morman churches? - Plenty.
