Some more info. I'm itching to get the 2012 Uk charity report to see if it reveals the big loss of the year that I've seen. In the meantime:

Glossary: RM (Returned missionary)
"... Other trends include:
(Most info taken from Ldschurchgrowth.blogspot.com and Cumorah.com ):
-The drop-out rate/retention rate among RMs is disturbingly high.
– This year, the church experienced it’s first Stake Shutdown, or First Stake Consolidation In Australia
-The number of actual convert baptisms has decreased almost steadily since the 80′s. This is based on the annual statistical report delivered in Gen. Conference.
-Most of the growth of “The Church” continues to be natural growth, through births rather than conversions. However, baptisms of children-of-record are declining too.
-Growth of Mormonism in the North America and Europe is virtually flat and is actually declining in some countries (prompting the shift from European missions to South American ones.)
- With the exception of new “minority” wards being created in some inner cities, Mormonism is dying off in urban centers, even in SLC.
- Most conversions to Mormonism are in the Third World, and the drop-out rate in those countries is very high. Surveys done in Mexico, Chile, and Brazil indicate that less than 20% of the “members” claimed by “The Church” self-identify as Mormons."
