Scranton is the sixth-largest city in the Commonwealth of Pennsylvania. It is the county seat and largest city of Lackawanna County in Northeastern Pennsylvania's Wyoming Valley and hosts a federal court building for the United States District Court for the Middle District of Pennsylvania. With an estimated population in 2019 of 76,653, it is the largest city in northeastern Pennsylvania and the Scranton–Wilkes-Barre–Hazleton, PA Metropolitan Statistical Area, which has a population of about 570,000. The city is conventionally divided into nine districts: North Scranton, Southside, Westside, the Hill Section, Central City, Minooka, East Mountain, Providence, and Green Ridge, though these areas do not have legal status.
Scranton is the geographic and cultural center of the Lackawanna River valley and northeastern Pennsylvania, and the largest of the former anthracite coal mining communities in a contiguous quilt-work that also includes Wilkes-Barre, Nanticoke, Pittston, and Carbondale. Scranton was incorporated on February 14, 1856, as a borough in Luzerne County and as a city on April 23, 1866. It became a major industrial city, a center of mining and railroads, and attracted thousands of new immigrants. It was the site of the Scranton General Strike in 1877.
People in northern Luzerne County sought a new county in 1839, but the Wilkes-Barre area resisted losing its assets. Lackawanna County did not gain independent status until 1878.
