Which is growing fast? Protestantism or Catholicism?

Protestantism means all the sub-branches in it
By total numbers, Protestantism is far behind Catholicism..But which has high percentage growth

Neither.

Evangelistic non-denominational is far faster growing than "protestant" and "catholic" combined.

Catholicism is not Christian. Catholicism cannot get anyone into heaven, because Catholicism teaches works for salvation.

hopefully none of the above.

Born again Christians are a part of Protestantism. last I heard Christianity was on the decline, if it is growing its the finder sects that are, because of poor education.

Catholic countries have much higher birth rates --not in Europe where they are about the same, but it is mainly because of Latin America's high birth rates.

How can you 'thumbs down' population statistics???
Oh wait, this is R&S. That explains it. The thumbs down people probably don't even know that Mexican-Americans (Catholics) are the fastest growing segment of the US population!

Did you mean 'faster'? Because 'fast' is subjective term.

Protestantism for sure, but that's due to the rigidity of Catholicism. Catholicism is still the largest sect though.

And yet atheism outgrows all of them

Faith,
