The Church in the United States has experienced significant deceleration in regards to increases in the number of congregations (e.g. ward and branch) thus far in 2017. Currently the Church in the United States reports a net increase of only 11 congregations thus far in 2017. To contrast, the Church in the United States reported an annual net increase of 65 congregations in 2016, 142 congregations in 2015, 152 congregations in 2014, and 124 congregations in 2013. Historically, the Church in the United States has generally reported a net increase 30-50 congregations during the first four months of the year, and a net increase of 100-150 congregations per year.
A decrease in the rate that new congregations have been organized appears primarily responsible for decelerating congregational growth rates in the United States thus far in 2017. Additionally, the rate that congregations have been consolidated or closed has remained consistent, resulting in smaller net increases in the number of congregations. The Church has also emphasized better utilization of church meetinghouses in the United States and other areas of the world. As a result, the Church has encouraged larger numbers of congregations to share the same meetinghouse and for congregations to have larger numbers of active members in order to conserve meetinghouse maintenance and building costs. For example, in some areas the Church is striving for sacrament meeting attendance to comprise at least 75% of seating available in a meetinghouse. Consequently, the Church has combined smaller congregations in order to reduce the number of meetinghouses needed.
The Church in the United States has also appeared to baptize fewer converts and report a lower birth rate as evidenced by slowing annual membership growth rates. The increasing influence of secularism on American society, particularly in the western United States, appears primarily responsible for these trends. LDS membership in the United States increased by a mere 0.93% during 2016 - the lowest in nearly 30 years. Rates for member resignation, excommunication, and deaths have appeared to be constant during the past few years based upon reports I have received from local and regional church leaders in several areas of the United States. Thus, the Church has reported smaller net increases in the number of members on its records for the United States.
