History and development

Established in the early 19th century from portions of neighboring counties, the area grew rapidly with the advent of canals, railroads and natural-resource industries. Iron, cement and later manufacturing and distribution have played major roles in the county's economic life. Over time the economy diversified toward healthcare, education, retail and logistics.

Today the county hosts colleges, cultural institutions, museums and regional medical centers. Parks, trails and preserved open space provide recreational opportunities while a range of performing arts venues and community festivals reflect a varied cultural scene.

• Transportation: served by interstates and regional arteries and by Lehigh Valley International Airport.
• Economy: mix of manufacturing legacy, logistics, healthcare and services.
• Government: county government based in Allentown administers courts, public records and local services.

Lehigh County's location between larger metropolitan corridors has made it a regional hub for commerce and commuting. Its history of industrial innovation, followed by broader economic redevelopment, is typical of many northeastern U.S. counties that transitioned from heavy industry to a more diversified, service-oriented profile.
