Swarthmore is a borough in Delaware County, Pennsylvania, United States. Swarthmore was originally named "Westdale" in honor of noted painter Benjamin West, who was one of the early residents of the town. The name was changed to "Swarthmore" after the establishment of Swarthmore College. "Swarthmore" can be pronounced with the first "r" either vocalized or dropped due to differences in rhotic and non-rhotic accents, but locally it is usually pronounced without the first "r". The borough population was 6,194 as of the 2010 census.
