Neighborhoods
Philadelphia has many neighborhoods, each of which has its own identity. The large Philadelphia regions, North, Northeast, Northwest, West, South and Southwest Philadelphia surround Center City, which follows the original borders of Philadelphia prior to consolidation in 1854. Numerous smaller neighborhoods within the areas coincide with the borough, townships, and other communities that made up Philadelphia County before their absorption by the city. Other neighborhoods formed based on ethnicity, religion, culture, and commercial reasons.
