The angle of the death spiral of the U.S. Catholic Church

Using the data in the post on The Growing Mystery of the 'Missing' Catholic Infants at the Nineteen Sixty-four blog, it appears U.S. Catholic baptisms as a proportion of total U.S. births have declined about 40% in 46 years [33.9% in 1965 to 20.1% in 2011]. I calculate that if this decline continues at that rate, the percentage will be 0% by around 2080. The post says,

"I am often one to caution overreactions to any piece of data. But its hard not to think that there is a pressing need to solve this mystery."

And yet it's hard to cite evidence that our bishops or priests or paid staff think this is a pressing problem. (My usual benchmark for "pressing" is an effort commensurate with a fund-raising campaign.)
