A new stake has been created called the Star Idaho Stake. This was created by splitting off from the first area I served on my mission, Meridian, which earlier was announced to get a temple. This is Idaho's first new stake of 2011. There are now 122 stakes in Idaho, California has 158 and Arizona has 91. There are now 1,494 stakes in the US (50.8%) for a total of 2,941 worldwide. There have been 38 stakes created in 2011, 21 of them in the US.
