For those of my followers who may be interested in "extreme cases" in church growth (positive or negative), the Church in Cote d'Ivoire is currently experiencing some of the most rapid growth that I have ever observed in the worldwide Church. In 2014 alone the Church has organized seven new wards and one new branch in the Abobo Cote d'Ivoire Stake, thereby doubling the total number of congregations in the stake to 15 wards and one branch. As congregational growth serves as one of the most robust indicators of "real growth" (i.e. increasing numbers of active members, improving maturity in priesthood leaders, high convert retention), this development stands as one of the greatest successes in terms of rapid growth within the worldwide Church ever documented. I am aware of no other instance of so many wards being created within a single stake within less than a year. To make this achievement even more impressive, the Church in Cote d'Ivoire has been entirely self-sufficient in meeting its full-time missionary needs through local and regional missionary manpower. Just this last summer the Church organized a second mission based in Abidjan to help better administer recent rapid growth experienced throughout the country.
As for some history with this particular stake, the Church organized the Abobo Cote d'Ivoire Stake in 2000. The stake was divided in 2006 along with the original Abidjan Ivory Coast Stake to create the Cocody Cote d'Ivoire Stake. No new wards or branches were organized in the Abobo Cote d'Ivoire Stake between 2006 and 2013, which may indicate that all of the recent new units organized were long overdue.
With six stakes and 57 wards in the Abidjan area, the Church appears posed to have as many as 10 stakes within the next five years.
