While Cabrini–Green was deteriorating during the postwar era, causing industry, investment, and residents to abandon its immediate surroundings, the rest of Chicago's Near North Side underwent equally dramatic upward changes in socioeconomic status. First, downtown employment shifted dramatically from manufacturing to professional services, spurring increased demand for middle-income housing; the resulting gentrification spread north along the lakefront from the Gold Coast, then pushed west and eventually crossed the river. Then, in the 1980s, the Lower North Side industrial area (just across the river from the Loop, west of Michigan Avenue, and south of Near North Side's Cabrini–Green) was transformed into the "River North" neighborhood, a focus of arts and entertainment, now home to the city's technology sector. By the 1990s, developers had converted thousands of acres of former industrial lands near the north branch of the Chicago River (and directly north, south, and west of the former Cabrini–Green projects) to lucrative office, retail, and housing developments.
