Like many other mainline Protestant denominations in the United States, the United Methodist Church has experienced significant membership losses in recent decades. At the time of its formation, the UMC had about 11 million members in nearly 42,000 congregations. In 1975, membership dropped below 10 million for the first time. In 2005, there were about 8 million members in over 34,000 congregations. Membership is concentrated primarily in the Midwest and in the South. Texas has the largest number of members, with about 1 million. The states with the highest membership rates are Oklahoma, Iowa, Mississippi, West Virginia, and North Carolina.
