I decided to go through the reports of the April general conferences since 1974 and track the number of converts reported each year. I noticed some interesting things.
First of all, there was a huge amount of growth from 1974-1990. The bulk of this time was under President Kimball’s administration and five years of it was under President Benson’s.
Second, there appear to be small pockets of growth decline every few years.
Third, from 1978 to 1982, the reported number of converts was rounded to the thousands place (152,000, 193,000, etc).
Finally, and perhaps most notably, the number of converts has been on a general decline since 1990, when it had reached a record 330,877 converts. In fact, last year, the number of converts reported was at the lowest it has been in 16 years.
UPDATE (02 April 2006): Added 2005 stats. Annual growth for 2003?¢‚Ç¨‚Äú2005 has been stable at roughly 240,000. I could not find stability trends in other years.
UPDATE (31 March 2007): Added 2006 stats. Convert growth is back on the rise.
