Southern Baptist Recent Stats of Concern

Found this in an article about a book review on the Southern Baptist Convention in Christianity Today:

"Annual baptism statistics have remained relatively steady for several decades, despite substantial American population growth. Studies show that less than 40 percent of the convention's 16 million members attend worship regularly. Statistics also point to a plateau in membership, including a decline in total membership in 2006."

Could this be due to the emphasis on inflated number, rush to baptize and lack of discipleship?
