According to the 2000 Census, the community has a population of 22,282. 81% of the South Park population is African American, compared to 25% for the city as a whole. Houston's Martin Luther King Boulevard runs through the area. Reflecting its postwar origins, many streets in South Park are named after World War II battle sites and persons. In the 1980s and 1990s crime became a key issue for South Park. Katharine Shilcutt of the Houston Press said "South Park is an overgrown garden these days, its soil only able to be tilled by the most determined or the most desperate. It shows no sign that it will grow again any time in the near future."
