Story

According to the U.S. Census Bureau, Allegheny County has a total area of 745 square miles - 730 square miles is land, and 15 square miles (1.95%) is water.

Allegheny County is known for the three major rivers that flow through it - the Allegheny and Monongahela converge at Downtown Pittsburgh to form the Ohio. The Youghiogheny River flows into the Monongahela at McKeesport, 10 miles southeast. Several islands are located within the river systems. Water from these rivers eventually flows into the Gulf of Mexico via the Mississippi River. Although the county's industrial growth caused the clearcutting of forests, a significant woodland remains.

As of the 2010 Census, there were 1,223,348 people residing in Allegheny County. The population density was 1676 people per square mile. The racial makeup of the county was 82.87% White, 14.39% Black or African-American, 2.94% Asian, 0.03% Pacific Islander, 0.37% from other races, and 1.40% from two or more races. About 1.31% of the population were Hispanic or Latino of any race.
