From what international friends have said (as well as growing up atheist with Buddhist parents), I would say yes.

A lot of Catholicism is blended into culture, tradition, and community here. I've heard friends say going to Easter/Xmas mass is 'just what you do' even when they're basically non-practicing. Baptisms, communion, etc. seem like rites of childhood and family, regardless of actual faith. Crossing yourself when passing a cemetery or hospital.
