As of the 2020 Census, Allegheny County, Pennsylvania, had a population of approximately 1.24 million residents. It is the second-most populous county in Pennsylvania, following Philadelphia County. The population may have changed slightly since then, so for the most accurate and current figures, checking the latest estimates from sources like the U.S. Census Bureau is recommended.
