What proportion of global Christians belong to denominations that accept evolution? I would like to know what percentage of Christians globally belong to denominations which accept evolution of humanity by natural selection (including "theistic evolution"). I can try to calculate these numbers by crossreferencing numbers at Wikipedia "List of Christian denominations by number of members" and "Acceptance of evolution by religious groups", but I'd rather see a published figure somewhere. 

I can see a lot published about the percentage among American Christians, but I think this is skewed by fundamentalists in America who are out of step with the global church on this issue. I want to say: X% of global Christians belong to a church which accepts evolution. This would include all Catholics and Orthodox, all Methodists, no Southern Baptists, etc. Just how many is that?
Answering my own question just in case anybody cares about this topic. This is totally unscientific, just cobbled together from wikipedia and googling. I am still interested in hearing an actual figure from experts. I spent about 20 minutes going through wikipedia articles "Acceptance of evolution by religious groups" and "List of Christian denominations by number of members", plus googling for position statements for the major denominational groups.

Results: out of 2.42 billion Christians globally (I excluded LDS), at least 1.7 billion belong to denominations with official statements that allow for some kinds of "theistic" evolution as the mechanism for God's creation of humanity. The true figure is probably higher, almost certainly not lower (I only checked the groups with big membership- anyone I didn't check is by default being left out of the 1.7 billion figure.) As a percentage, at least 73% of global Christians belong to denominations which allow for some kind of evolution as the mechanism for the creation of humanity.
