There's contradictory information available. A book entitled "Why Catholics Don't Give, And What Can be Done About It" by Charles Zech, Chair of the Economics Department at Villanova University.
Quoting from that book, "Annual household donations by Catholics are only one-third of the donations given by Assemblies of God members, one-half of the donations of Baptists and Presbyterians, and well below donations of Lutherans."
http://www.philanthropyroundtable.org/topic/excellence_in_philanthropy/stepping_up_to_the_collection_plate"Still, as the title of this book suggests, Catholics do not give either to their Church or to other charitable causes at nearly the level that might be expected, given their affluence. This despite clear Church teachings that emphasize both denominational and individual responsibility for the poor.
How bad is it? Catholic households give barely more than 1 percent of their income to their Church—about half of what most mainline Protestant families give, and far below what Jewish, Mormon, and more evangelical Protestant households contribute."
Also, the footnote to your list says "* Catholic Church Giving is a very rough estimate. "
http://donsnotes.com/society/donations.htmlYou know, I think this is one of those things that would be greatly difficult to track. Especially when there is no specified criteria for the data being selected. When it comes to giving per household, it appears that the non-Catholics give at a higher rate. The Mormons blow us all away percentage/household wise. When it comes to denominations giving to charities, then it looks like the Catholic church gives at a higher rate.
But, I question how the contributions that are given to charities by individuals directly rather than going through their church is counted (I suspect the answer is that it is not in these figures). When you send money and goods to Haiti directly or to an organization geared to collect for the specific trauma, the organization doesn't require you to enter your denomination so those are contributions that are never 'credited' to a denomination.
I think it safe to say, that few of us give at the level that we should and that many of us live at a higher level than is needed.
