I've heard that countries that kept better records of their population had more Jews captured by invading Nazis than those countries that had worse records. I don't seem to be able to find hard evidence for that though, so maybe it's not true.

Still, I think it's clear that data can very quickly go from harmless to harmful depending on who gets their hands on it. The Nazis absolutely did have a problem finding all the Jews they wanted to kill, and abundantly available data about the religious preferences of literally every citizen being immediately available to them would absolutely have caused much more death than already happened.
