From Our Sunday Visitor's story on unsettling findings from the Center for Applied Research in the Apostolate (CARA): "A new survey conducted by the Center for Applied Research in the Apostolate (CARA) at Georgetown University indicates that more than three in four adult Catholics in the United States are not aware that aspects of the English translation of the Roman Missal are about to change. [The] survey estimates more than four in 10 weekly attenders have not heard that the words and prayers at Mass will be changing. Respondents were asked if they had heard 'that parishes in the United States will soon be implementing changes in the words and prayers at Mass at the direction of the Vatican.' Seventy-seven percent answered 'no.' This is equivalent to more than 44 million adult Catholics who don’t know about the changes that will occur throughout the English-speaking world beginning Nov. 27, the first Sunday of Advent."
Anecdotally, this has been my experience as well. When I ask the average Massgoing Catholic what they know about the new English translations, the most common response is, "Huh?" More about the CARA survey here.
This comes despite an effort on the part of the U.S. Bishops to educate the faithful about the new changes. Their website on the changes is here. One group of Catholics on the other hand has launched their own website called "Misguided Missal," which takes a somewhat different tack from the bishops.
