Documenting the Rate of Western Migration

The images below show the center of US Population for the years 1790 to 1890, based on the US census. In 1790, the center of US population was about 25 miles east of Baltimore. By 1820, the center of US population had moved approximately as far west as the Michael Korn farm in Southampton Township, Somerset County, PA. In other words, in 1790 Michael Korn was a pioneer in the wilderness, but by 1820, half of the US population had migrated west of Michael Korn. This massive western migration may have served as an important market for Michael Korn's farm goods, and may have helped make him the relatively prosperous man that he was. The images are from the 1901 book "The Leading Facts of American History" by D. H. Montgomery.
