Statistics about Christianity and their relation to Science and Evolution

Gathered these facts in 2013.  Never posted.  Not sure why, but as they are still valid (for the time they were gathered -- unlikely to have changed since 2013)  and pertinent to a discussion I was having, I'll post now.

Pope John Paul II reaffirmed the Catholic stance that the theory (or theories) of evolution are not in conflict with scriptural truth (see Message to the Ponfical Academy if Sciences: On Evolution) and in fact, the centuries-old recognition that "We know that the truth cannot contradict the truth. (Leo XIII, Providentissimus Deus)"

Here are two important things for people involved in the "Church vs. Science" false debate to take from the above:

Christians -- you are not the minority.  Many Christians speak, act, and even stand in pulpits and preach as if they were somehow the minority.  While it is true that there are more non-Christians in the world than there are Christians, of people professing a religion, you are the largest group.

People who claim "Christians are opposed to science and particularly the Theory of Evolution": The numbers above demonstrate that a majority of Christians in the world profess a type of Christianity which supports the Theory of Evolution, and has done so for decades.  And that's only the Catholics.  There are plenty of Christian denominations which are not Catholic, but which also acknowledge that "truth cannot contradict the truth" and that, to the best knowledge humans have today, Evolution is scientific truth.

While researching this, I came across an essay by Doug Linder: The Vatican's View of Evolution: The Story of Two Popes, which I found very interesting.  It selected some of the key quotes from two Popes, which show the progression of acceptance of evolution in that branch of Christianity.
