Some interesting stats from the book The American Church In Crisis by David T. Olson…(not that this is accurate but…)

1) Less than 20% of Americans regularly attend church – half of what the pollsters report. There are approximately 330,000 churches in America; out of those churches approximately 17.7% (52 million) of Americans attend church on an average Sunday.

2) American church attendance is steadily declining.
• Evangelical 9.2%
• Catholic 5.5%
• Mainline 3.1%

3) Only one state is outpacing its population growth. Hawaii.

4) Mid-sized churches are shrinking; the smallest and largest churches are growing.
• Churches under 50 and over 2,000 are growing
• Average attendance of Protestant church: 124
• 1,250 mega-churches in America/one emerges every three days

5) Established churches, 40-190 years old – are, on average, declining. New church starts reach more people better, faster, cheaper than existing churches.

6) The increase in churches is only ¼ of what’s needed to keep up with population growth.
• 3,000 churches close every year
• 3,800 new church starts survived
• Net annual gain: 800 new churches
• Net annual gain needed to keep up with population growth:10,000 new churches

7) In 2050, the percentage of the U.S. population attending church will be almost half of what it was in 1990.
• US Population in 1990: 248 million/20.4% church attendance
• US Population in 2050: 520 million/11.7% church attendance
