When they originally opened, both West Catholic Girls and West Catholic Boys served students from West Philadelphia, Southwest Philadelphia and Delaware County. As more Archdiocesan high schools opened in the suburbs in the 1950s and 1960s, West's "feeder schools" became limited to parishes in West and Southwest Philadelphia. With the advent of "open enrollment" for Archdiocesan high schools in the 1990s, West Catholic continued to draw from West and Southwest Philadelphia, and also attracted students from Philadelphia and its suburbs. Currently (2011), approximately 25% of the students come from suburban areas, with the other 75% from across the City of Philadelphia.
