Lancaster County Anabaptist community founded in c. 1760, has the world's largest [[Amish]] settlement, with 37,000 people in 220 church districts in 2017, or about 7% of the county's population.<ref name=update>[http://amishamerica.com/12-largest-amish-communities-2017/ The 12 Largest Amish Communities (2017).] at Amish America</ref> By 2021 the Amish population increased to almost 42,000.<ref name="Elizabethtown College, the Young Center for Anabaptist and Pietist Studies-2021">{{Cite web |url=https://amishamerica.com/2021-amish-population/#maincontent |title=The Amish Population in 2021 |date=August 12, 2021 |website=Elizabethtown College, the Young Center for Anabaptist and Pietist Studies |access-date=August 22, 2021 |archive-date=August 12, 2021 |archive-url=https://web.archive.org/web/20210812190707/https://amishamerica.com/2021-amish-population/ |url-status=live }}</ref><ref>[http://groups.etown.edu/amishstudies/files/2021/08/Amish-Pop-2021_by-state-and-county.pdf Amish Population in the United States by State and County, 2021]</ref> The [[Lancaster Amish affiliation]] is relatively liberal concerning the use of technologies compared to other Amish affiliations.

Historically speaking, the Amish population in 1970 numbered only about 7,000; that climbed to about 12,400 by 1990 and 16,900 by 2000.<ref>{{cite web|url=https://lancasteronline.com/news/local/amish-population-grows-by-a-year-despite-lancaster-county-s/article_e24c564e-678e-11e9-9ba4-bf1905bae642.html|access-date=May 7, 2019|title=Amish population grows by 1,000 a year, despite Lancaster County's urban sprawl, development|publisher=Lancaster Online}}</ref> It has doubled since then.

Lancaster also hosts other [[Plain dress|Plain]] [[Anabaptists|Anabaptist]] groups. As of 2000, there are about 3,000 [[Old Order Mennonite]]s of the [[Groffdale Conference Mennonite Church|Groffdale Conference]] who drive black top [[Amish buggy|buggies]] instead of the grey top buggies of the Amish in Lancaster County. Other buggy-using Old Order Mennonites in Lancaster County are subgroups of the [[Stauffer Mennonite]]s with 283 baptized members and the [[Reidenbach Old Order Mennonites|Reidenbach Mennonites]] with 232. There are about 4,000 members of the car-driving [[Weaverland Old Order Mennonite Conference]]. A congregation of 83 members of the [[Old Order River Brethren]] lives there as well as 84 members of the [[Reformed Mennonite|Reformed Mennonite Church]] who have retained the most conservative form of Plain dress of all Plain groups. There are 74 members of the [[Old German Baptist Brethren]] in Lancaster County.<ref>Donald B.
