I've seen some reports of small growth in the catholic Church (something 1 1/2 %), but I think this is more accurate:
2. American church attendance is steadily declining.
In 1990, 20.4% of the population attended an Orthodox Christian church on any given weekend. In 2000, that percentage dropped to 18.7% and to 17.7% by 2004. Olson explains that while church attendance numbers have stayed about the same from 1990 to 2004, the U.S. population has grown by 18.1%—more than 48 million people. “So even though the number of attendees is the same, our churches are not keeping up with population growth,” he says.
Well-known church researcher and author Thom Rainer notes that the failure of churches to keep up with the population growth is one of the Church’s greatest issues heading into the future. In a 2002 survey of 1,159 U.S. churches, Rainer’s research team found that only 6% of the churches were growing—he defines growth as not only increasing in attendance, but also increasing at a pace faster than its community’s population growth rate. “Stated inversely, 94% of our churches are losing ground in the communities they serve,” he says.

The most significant drop in attendance came at the expense of the Catholic Church, which experienced an 11% decrease in its attendance percentage from 2000 to 2004. Next, and not far behind were mainline churches, which saw a 10% percentage decline. Evangelicals experienced the smallest drop at 1%.
