The Northwestern district is mostly residential. It is also home to the Pimlico Race Course and Sinai Hospital. Until the 1960s, Baltimore's Jewish community was based in the Park Heights neighborhood. Since then, there has been "white flight" and the neighborhood today is almost all black. Northern Parkway is a dividing line in the district. North of the parkway, the neighborhoods are mostly white. Some of these are Mount Washington and Cheswolde. South of the parkway, the neighborhoods are mostly black. The borders of the district are made up by the county line on the north and west, Gwynns Falls Parkway on the south and Pimlico Road on the east.
