After a lot of searching, I was surprised to not find any graphs with the information I wanted, so I decided to make them myself.
Below you will find graphs displaying data about the number of missionaries and missions of the Church of Jesus Christ of Latter-day Saints (formerly nicknamed “the Mormon church”) from 2009 to 2019. In particular, this time range includes the 2012 announcement lowering the age limit for when men and women can go on missions. This announcement resulted in what is often called “the Missionary Boom,” a large increase in the number of missionaries serving missions and the number of missions that they are serving in. All data was collected from statistical reports published in the year following the year being reported on (e.g., data for 2013 was collected from the Church’s April 2014 statistical report).
