"...and I would say 90% of the baptized Catholics [5.5 million] no longer attend church."

It is hard to say. My  sources are academics, Australian Catholic. They are more hopeful. They will note that like the French Church, the Australian Church has similar stats only the French use different categories: "cultural Catholics," "seasonal," "Vatican II Catholics," "observant," "inspired Catholics," and "emancipated" (self-identified Catholics very left and more active in civil movements than church activities). "No longer attend" means one no longer attends a weekly service. Like the French bishops (who praised the secular survey, finding it reflected the French Church's "rich diversity") the Aussie academics are optimistic (especially about Catholic educational institutions). I guess it depends on who you talk to, their background, class, immigrant/non-immigrant status, and so many, many other factors, including whether one or someone in one's family was abused.
Anyway, they're hopeful.
