The United Methodist News Service shares the latest numbers on the UMC in the USA: Mixed blessings in new U.S. church numbers.
Here are the numbers.
The report from the General Council on Finance and Administration found membership in the United States now at 7,570,980. …
Statistics as reported by local churches and annual conferences indicate that professing membership in 2010 was down 1.4 percent from 2009, and average worship attendance was down 2.3 percent. In 2009, membership decreased 1.2 percent and attendance, 1.9 percent.
In 2005, The United Methodist Church established two categories of membership –– baptized and professing. A total of 140,295 persons were received in United Methodist congregations on “profession of faith” or “faith restored” in 2010, a 1.4 percent decline from 2009.
The 2010 report indicates only 54 percent of churches reported receiving any members by profession of faith or faith restored, down from slightly more than 58 percent in 2005.
The good news in the story had to do with donations to UMCOR and other causes. The story also points out that our decline mirrors the rest of mainline Protestantism.
For those with an interest in history, here are the historical statistics on membership in the USA since 1790.

This love we believe to be the medicine of life, the never-failing remedy for all the evils of a disordered world, for all the miseries and vices of men. Wherever this is, there are virtue and happiness going hand in hand. There is humbleness of mind, gentleness, long-suffering, the whole image of God; and at the same time a peace that passeth all understanding, and joy unspeakable and full of glory.
In 1970, United Methodists were 5.9% of the population. By 1980, membership declined by 10.8% and was 4.2% of the population. Going to 1990, membership declined by 7.0% and was 3.6% of the population. From 1990 to 2000, membership declined by “only” 4.9% and was 3.0% of the population. In the last ten years, membership has declined by 10%(!) and is now only 2.5% of the population. The actual membership number is less than (the combined) number in 1930! We haven’t represented a smaller proportion of the population since 1840!
