The border of Baltimore city is shown on this map by an olive green line. Baltimore is officially divided into nine geographical regions but locals usually divide the city between East and West using Charles Street (I-83 highway) as the dividing line and between North and South using Baltimore Street as the dividing line. Some areas are principally upper-middle class suburbia, others are home to young urban professionals and yet others are poor socio-economically disadvantaged areas blighted by violence and the drug trade.
