On the other hand if I asked "do many Catholics worship Mary" and you again said "no" (citing Catholic dogma) I would say you were throwing up a smoke screen, disowning so many "Catholics" you would substantially reduce the number of Catholics, generally claimed to be approximately 1.2 Billion. Do you have any surveys that document the many Catholic who affirm that they worship Mary? I have lived my whole life in the Catholic Church and I have never met a single Catholic who worships Mary. If, by chance, you do meet such a one please inform him that such practice is condemned by the Church and contrary to our faith. It is dishonest, however, to present to the world as Catholic faith what the Church herself condemns.

Of course not, it is not something the Catholic Church would study or publish. The only "evidence" available are from ex-priests, ex-Catholics, and non-Catholic (some hate sites) sources. The record shows it has been, and is, particularly prevalent in Central and South America.
A Google search on "worship of Mary" will prove interesting.
