In 2020, Lancaster County Moved Left, But its Rural Areas Moved Right

As in most Pa. counties, Democratic votes grew faster than Republican votes from 2016 to 2020, causing the county to shift slightly left. But rural parts of the county defied that trend, with far larger Republican vote growth.

Precincts were grouped geographically by population density, educational attainment, and racial makeup. Precincts with fewer than 291 adults per square mile were classified as rural; those with between 291 and 2000 adults per square mile were classified as suburban; and those with more than 2000 adults per square mile as urban. Urban precincts were further divided by whether they had a white or non-white majority adult population. The white-majority areas were split by whether more or fewer than 40% of adults had a bachelor's degree.
