Arnold, Pennsylvania

Geography and layout

The city lies within the landscape of Allegheny Plateau communities that surround Pittsburgh, and it is closely connected by road and commuter routes to nearby boroughs and suburbs. Its compact size produces a mixture of residential neighborhoods, small commercial strips and municipal facilities within a limited urban footprint.

History and development

Arnold developed during the era when southwestern Pennsylvania expanded rapidly because of coal, steel and other manufacturing industries. Like many towns in the region, the city grew to house workers and their families and to support industry-related services. Over the later twentieth century, changes in manufacturing led to population and economic shifts, and Arnold adapted by refocusing on community institutions and housing for commuters.

Economy and community life

The local economy combines small businesses, light industry, and service providers alongside residential streets. Schools, churches, civic groups and neighborhood organizations contribute to community life. Many residents commute to jobs elsewhere in the metropolitan area while others work in local enterprises.
