Along with the automobile, they reject many modern conveniences, while allowing electricity in their homes and steel-wheeled tractors to till the fields. Initially concentrated in eastern Lancaster County, Pennsylvania, their numbers had grown to 22,305 people resided in eight other states as of 2015.
