The departure of the steel industry, along with other manufacturing jobs from the South Side in recent decades, has created economic difficulties which the area is still trying to overcome. The district's median household income as of 2000, $37,222, trailed the national average by 11.4%. The unemployment rate (7.6%) was more than double the national rate, and nearly 20% of district residents were living in poverty. These problems are more pronounced within the Chicago portion of the district – 14 of the district's 18 suburbs had median household incomes over $40,000 as of 1999, with the six most affluent grouped in the southwest corner of the district. But black middle-class Chicago neighborhoods, such as Avalon Park and Chatham, have remained more stable, along with the more upscale Hyde Park-Kenwood area. Health care and higher education now constitute major economic sectors in the region.
