A new survey has found that only 14% of Catholics actually attend Mass regularly, according to Cath News:
"The Australian Catholic Bishops Conference Pastoral Projects Office conducted a national count in May 2006, which showed the total number of people at Mass on a typical weekend was 708,600, or about 14 percent of the Census Catholic population. This was down from a little over 15 percent, or 764,000, in 2001.
Meanwhile, the 2006 Australian Census showed that Catholics remain the largest religious group in the country. There were 5,126,884 Catholics in Australia, making up 25.8 percent of the total population of 19,855,288. The next two largest groups in terms of religious affiliation were Anglicans and those who said they had no religion, with both accounting for 18.7 percent of the population.
The Catholic population grew by 125,260 between the 2001 and 2006 censuses, but declined slightly as a proportion of the total population from the 2001 figure of 26.6 percent."
The Survey also found that 'Mass attenders are on average older, better educated and more likely to be female, married and born overseas than Catholics in general'.
The median age of mass attenders was 58 - there weren't (as far as I can tell) any TLM communities, where large young families predominate in the survey, and in any case people under 15 were excluded from the figures.

But in any case, I think it identified a pretty clear target group for re-evangelization....
