Scientifically speaking... Which is what an "...estimate..." of anything should be founded upon... There is no such thing as "...Catholic...", just as there is no such thing as Baptist, Lutheran, Pentecostal, or any other Christian denominational being claim, or even a claim of being a Muslim, or any other type related to any religion... In regards to the being of any human.
Just check the DNA of any human... You will find no scientific fact that supports a claim of being anything related to religion.
Therefore... Any "...estimate..." presented regarding human relationship to any religion is just, scientifically speaking, fallacious.
Now... What is accepted as scientific is metaphysics, which is a branch of philosophy that examines the basic structure of reality.
According to the mighty Wikipedia (I say that somewhat tongue-in-cheek)... "Metaphysics is traditionally seen as the study of mind-independent features of the world (my explanation... things that exist apart from any mind... facts that simply are and have always been), but some modern theorists understand it as an inquiry into the conceptual schemes that underlie human thought and experience (my explanation... these independent facts influence human thought and experience)."
So, if we really want to know the underlying cause of any population and its relationship to human-contrived religion... We need to delve into the science of philosophy, specifically, that of metaphysics.
Historically speaking... Those in the colony of Haiti, who carried out the rebellion against the French that later became the Haitian War of Independence, did so by utterly rejecting the Roman Catholic religion that was the religion of the French who were being rebelled against. The Pope at that time would have been in support of the French, not the rebellious slaves... And so the rebellion was a rejection of the Pope... And to have rejected the Pope was akin to rejecting the religion the Pope headed up.
But this is a historical, not religious, discussion for another time... One that is crucial to the proper understanding of the present situation in Haiti and the mindset of Haitians.
Wonderful... All childbirth is a blessing to mankind... And perhaps the success of the DR economy is directly related to the grace and mercy being shown to the poor and the needy.
But if you're into eugenics you might think differently... Are you into eugenics Bob?
Again... It's wonderful that the DR can show such mercy and grace to the poor and needy.
May the DR continue to be blessed economically so that it can continue in such a benevolent way.
And, who knows... Should the DR take another course... Perhaps the economic success enjoyed by the DR may come crashing down.
There are no guarantees in life, Bob... Not even the further economic success of a country... Metaphysically speaking that is.
