Allegheny County, Pennsylvania

Allegheny County was once one of the nation’s most populous counties. And home to a prosperous manufacturing industry.

A metropolitan community of more than 1.2 million residents, Allegheny County is home to 130 municipalities, each with its own municipal governance. Pittsburgh is the county’s biggest city, representing 25% of the population and 13% of the county’s physical area. Outside of Pittsburgh, the surrounding 129 suburban municipalities are individually much smaller, each accounting for, at most, 4% of Allegheny County’s population.

After the collapse of the steel industry in the 1970s, the county’s population declined by 24% from its peak in 1960. Widespread financial hardship exacerbated disparities in education, employment, poverty, and access to care. Today, Allegheny is undergoing a transformation, driven by Pittsburgh’s efforts to revitalize the city center. Young people are moving in, attracted to jobs in the technology industry. However, issues like unemployment and poverty continue to disproportionately affect the region’s Black residents.
