"The Collapse of the Church in France
The IFOP Institute has just made a survey on Catholicism in France for the daily La Croix. The result is mind-blowing:
Whilst, in 1965, 81% of the French declared themselves as Catholics, they were no more than 64% in 2009.
More serious: whilst 27% of the French went to Mass once a week or more in 1965, they are no more than 4.5% in 2009.
At a doctrinal level, generally, it’s a catastrophe: 63% of practicing Catholics think all religions are the same; 75% ask for an “aggiornamento” of the Church on contraception and even 68% for abortion."

“Did the Decline of Catholicism in Post-Vatican II America Have to be So Steep and Is
the Climb Back Really So Improbable?: A Few Questions at the Margins

“Various social scientific studies of contemporary Catholics have revealed important
differences among generations. Older Catholics, especially those who came of age prior to
Vatican II, are typically more involved in Church life and attend Mass more frequently than
younger generations of Catholics. In general, they tend to score higher on most survey items that measure “commitment” to Catholicism. Knowledge about the Catholic faith also varies by generation and is frequently greatest among older Catholics. However, this depends on the topic. For example, knowledge of Church teachings and obligations is usually higher among older Catholics, but knowledge of the Bible is typically greater among younger generations. Agreement with Church teachings is, again, often relatively high among the oldest Catholics, the Pre-Vatican II Generation (born before 1943). To a lesser extent this is also true of the Millennial Generation, Catholics (born after 1981) currently in their mid-20s and younger. Agreement with Church teaching is typically lowest among the generation of Catholics whocame of age during the changes associated with Vatican II (born between 1943 and 1960) and among Post-Vatican II Generation Catholics (born 1961 to 1981) though this too depends on the
teaching in question.”
