About how many people do the Roman Catholic Church and Eastern Orthodox have & where

I can't find any information on an estimate on how many people are in the Roman and the Orthodox churches. Also I need to find out where their followers are mainly located in. Thanks

Catholic Adherents: ~ 1.3 billion worldwide
Orthodox Adherents: ~ 250 million world wide.

They are scattered everywhere in the world, however primarily:

Catholics: Western Europe & the Americas
Orthodox: Eastern Europe, parts of Africa, and Alaska.

There are about 1.1 billion Catholics. They are found all over the world. Eastern Orthodox are mainly located in Eastern Europe.

Catholicism is the largest of the 3 Christian denominations, & Orthodoxy is the smallest of the 3 denominations(though Protestants make numerous churches with all varying degrees points of view of Christianity).

Sorry, I don't know the exact numbers, but, Catholicism can be found mainly in Western Europe(the Phillipines is the only Catholic Christian nation in Asia), while Eastern Orthodox is predominant in Eastern Europe(where else?).

Catholicism is also predominant in Latin America.
