York County, Pennsylvania

York County lies in south-central Pennsylvania along the Maryland border, with York serving as its county seat and largest city. The Susquehanna River forms the eastern boundary, while rolling farmland, wooded ridges, historic boroughs and growing suburbs spread westward. Created in 1749, the county played notable roles in the Revolutionary era and later developed a strong manufacturing base. Agriculture remains visible across the countryside despite continued metropolitan growth. Manufacturing, logistics, health care, food production, tourism and regional commuting support the economy.
