Humboldt Park, located on the northwest side of Chicago, Illinois, is one of 77 officially designated Chicago community areas. The name is used to describe both the area as a community and the 207 acre (0.8 km²) park itself. The neighborhood has a diverse population and is home to a high concentration of Puerto Ricans. In conventional use, the neighborhood's borders include Western Avenue to the east, Pulaski Road to the west, Armitage Avenue to the north, and Chicago Avenue to the south. The Humboldt Park Community area, which many statistics about the area refer to, is west of these conventional borders. Its borders are the Belt Railway on the west, just east of Cicero Avenue; the Union Pacific tracks to the south, along Kinzie Street; Bloomingdale Avenue on the north; and Humboldt Boulevard, Humboldt Park, and Sacramento Boulevard on the east. The railyards southeast of Grand and Sacramento are also part of the Community area.
The racial/ethnic breakdown of the area is 48 percent Hispanic/Latino, 47 percent African American, 3 percent Caucasion, 1 percent Asian American/Pacific Islander, and 1 percent American Indian. The median household income is between $25,000 and $50,000. The Humboldt Park Community was selected for this intervention due to high rates of diabetes in the neighborhood.
