Catholic France is no longer what it was 15 years ago, with 51% of French people aged 18 to 59 still identifying as Catholic in the latest Ifop reading, down from 64% in 2010. Meanwhile, religious life keeps transforming in quieter ways, from falling weekly Mass attendance to a 17% share of students educated in Catholic schools. And as secularism hardens into law and daily practice, nonreligious identification rises too, setting up a country where religion, belief, and public space do not move in the same direction.
