This is from an excellent and short article over at the inexhaustible IBMR:
By the end of the twentieth century, Pentecostal and charismatic Christianity in all its diversity had expanded into almost every country on earth. It had become an extremely significant movement within global Christianity affecting Catholics, Anglicans, Protestants, evangelicals, and especially the independent churches in China, India, Africa, and Latin America. It is probably the fastest expanding religious movement in the world ever, certainly the fastest within Christianity.
