Recently, I became interested in seeing church attendance numbers over time. So I requested the numbers from the church office, and put them in a chart.
My church has two services. The one at 8:45 is traditional, and the 11:00 is contemporary.
There was another service at 11:00 in the gym from around 2006 to 2009. It became problematic to run both of these at the same time, so it ended. But in terms of attendance, it seems like the gym service was a good thing to have.
At the end of 2013, another church merged in with ours, and most of the new people chose to attend the 8:45 service.
This chart shows average monthly attendance (smoothing out the lowest and highest of the month):
Here is a chart showing average annual attendance:
*Easter and Christmas were omitted from the chart.
