A new census of the Amish population in the United States estimates that a new Amish community is founded, on average, about every 3 ½ weeks, and shows that more than 60 percent of all existing Amish settlements have been founded since 1990. This pattern suggests the Amish are growing more rapidly than most other religions in the United States, researchers say. Unlike other religious groups, however, the growth is not driven by converts joining the faith, but instead can be attributed to large families and high rates of baptism. In all, the census counts almost 251,000 Amish in the United States and Ontario, Canada, dispersed among 456 settlements, the communities in which members live and worship. The 1990 census estimated that there were 179 settlements in the United States. If the growth of the Amish population continues at its current rate, the Ohio State University researchers predict that the census could exceed 1 million Amish and 1,000 settlements shortly after 2050, and these numbers will bring economic, cultural, social and religious change to the rural areas that attract Amish settlement....No state has seen more recent growth in settlements than New York, where 15 new settlements have been established since 2010. But 34 of Ohio's 54 settlements have been founded since 1990, a trend that contributes to the state's large Amish population, Donnermeyer said. Ohio is also home to Holmes County, the U.S. county housing the highest percentage of Amish, with 42 percent. The Greater Holmes County settlement, which sprawls across six counties (Holmes, Wayne, Tuscarawas, Coshocton, Stark and Ashland), is the largest settlement, with nearly 30,000 Amish, followed by the Lancaster/Chester County settlement in southeastern Pennsylvania. "My guess is that in 15 years, we'll witness a county whose population is majority Amish, and Holmes County is likely to gain that distinction first. Perhaps LaGrange County in Indiana will not be far behind," Donnermeyer said
