After the assassination of Martin Luther King Jr. and the subsequent riots, the neighborhood experienced a tense racial division during the 1970s and 1980s which left a segregation between Old Town north of North Ave. and Old Town south of North Ave. In the early 2000s, this trend had begun to shift towards a gentrification of the area south of North Ave. on Sedgwick, Blackhawk, Hudson and Mohawk streets, near the Marshall Field Garden Apartments. The area to the west of these streets, near the North and Clybourn Red Line stop had been dubbed "SoNo" by real estate developers. SoNo's boundaries are North Avenue, Halsted Street, Division Street and the North Branch of the Chicago River. Currently, Old Town south of North Avenue is a mixture of wealth and poverty, though the area is steadily gentrifying. The demolition of the Cabrini–Green high rise housing projects to the south has led to significant demographic changes in the neighborhood. The original Francis X. Cabrini Row Houses still are standing. The Parkside of Old Town development was built replacing the Cabrini-Green high rises just south of Old Town.
