Some Elkhart County residents don't have a college degree out of principle.
Amish, Old Order Mennonites and other groups such as Old German Baptists usually go to school, either public or private, through the eighth grade. They usually avoid college altogether.
"They're not wanting to (go) because that will make them more English," said Joseph Yoder, director of Menno-Hof, an Amish-Mennonite visitors center in Shipshewana.
"English" is the term often used to describe conventional culture in the United States and the people who don't drive buggies.
Amish settlements cross county lines, so counting the number of Amish and plain Mennonites in Elkhart County is difficult, said Steve Nolt, associate professor of history at Goshen College.
Nolt, who has studied and written about the Amish extensively, estimated Elkhart County has 6,400 Amish people and another 1,000 people in other plain groups.
Nolt said an estimated 3,300 or so people in the two groups would be adults. That's 2.7 percent of Elkhart County's 120,546 people age 25 or older.
Even if all of them had gone to college, Elkhart County's overall percentages for high school and college graduation still would be significantly below the national averages.
An increasing number of Amish are taking advantage of manufacturing jobs and moving away from the traditional farm labor.
Yoder estimated only about 2 percent of Amish men are full-time farmers. Many are earning good pay in factories.
"There's still an incredible work ethic with the Amish. They get that from so young," he said.
