Maybe René Bekkers can help you out? He’s the director of the Center for Philanthropic Studies at the Vrije Universiteit in Amsterdam. They focus on EU + Dutch stuff, e.g., they contributed to the 2017 Giving in Europe report. You can find his email address here. I don’t know him well but he attended a small event we organised.
Perhaps it’s in the Giving USA Annual Survey? You need a subscription to access it though.
Hm yeah, I think the previous analysis was done on top of that report, so if anyone has access to it, it might be helpful.
