The pace at which new LDS stakes have been organized in 2011 has increased compared to the pace of stake organizations in other years over the past decade. No other year has experienced as many new stakes organized within the first six months of the year as 2011 since 1998 when the number of LDS stakes increased by 81 for the entire year. The annual change in the number of stakes operating in the Church ranged from a high of 47 in 2009 to a low of -5 in 2002. Currently the number of stakes has increased by 37 during 2011; a greater increase than all but four years for the LDS Church in the 2000s. At present 42 stakes have been created and five stakes have been discontinued in 2011. The increased rate of stake organizations in 2011 has been primarily attributed to the creation of ten new young single adult (YSA) stakes in Utah and the maturation of nine districts into stakes rather than the creation of new stakes from preexisting stakes. Notwithstanding the accelerated pace at which new stakes have been organized this year, the number of new stakes organized remains far below many years of more rapid growth between the late 1970s and late 1990s when the number of stakes regularly increased by over 50 a year and at times over 100. Increased church growth for the LDS Church may be demonstrated if the pace at which new stakes is organized continues to hold steady for the remainder of 2011 and in the coming years as certain standards for the number of active members are required for stakes to operate. However the rate at which new congregations are organized appears to be only a third of the rate at which membership is growing, suggesting that inactivity and retention challenges for new converts persist.
