not add up, because Hispanics are counted both by their ethnicity and by their race, giving a higher overall number. Since 2016, data for births of White Hispanic origin are not collected, but included in one Hispanic group; persons of Hispanic origin may be of any race. Languages In 2010 97.67% (1,697,042) of West Virginia residents aged 5 years and older spoke English as their primary language. 2.33% of residents spoke a mother language other than English. Religion Several surveys have been made in recent years, in 2008 by the American Religion Identity Survey, in 2010 by the Pew Forum on Religion and Public Life. The Pew survey results admit to a 6.5% margin of error plus or minus, while the ARIS survey says "estimates are subject to larger sampling errors in states with small populations." A characteristic of religion in Appalachian communities is the abundance of independent, non-affiliated churches, which "remain unnoted and uncounted in any census of church life in the United States". This sometimes leads to the belief that these communities are "unchurched". The largest denomination as of 2010 was the United Methodist Church with 136,000 members in 1,200 congregations. The second-largest Protestant church was the American Baptist Churches USA with 88,000 members and 381 congregations. The Southern Baptist church had 44,000 members and 232 congregations. The Churches of Christ had 22,000 members and 287 congregations. The Presbyterian Church (USA) had 200 congregations and 20,000 members. A survey conducted in 2015 by the Pew Research Center found that West Virginia was the seventh most "highly religious" state in the United States. A separate 2020 survey by the Public Religion Research Institute found that 69% of the adult population was Christian, reflecting a slight decrease since the Pew Research Center's 2015 survey. In 2020, a survey of nearly 1,900 West Virginians reported that 78.6% were Christian, and 16.2% were unaffiliated.
