Map of Chicago community areas.

Neighborhood polygons used by the Cook County Assessor's Office for valuation and reporting. These neighborhoods are specific to the Assessor. They are intended to represent homogenous housing submarkets, NOT Chicago community areas or municipalities. These neighborhoods were reconstructed from individual parcels using spatial buffering and simplification. The full transformation script can be found on the Assessor's GitHub. Read about the Assessor's 2025 Open Data Refresh.

Healthy Chicago Equity Zones is an initiative of the Chicago Department of Public Health (CDPH) to organize and support hyperlocal, community-led efforts that promote health and racial equity. Chicago is divided into six Equity Zones, through which the City collaborates with regional and neighborhood organizations to address issues of common concern – like COVID-19 vaccine distribution, health care access, violence prevention, and food security – and improve quality of life at the neighborhood level. The Equity Zones are the following. Far South: Beverly, Burnside, Calumet Heights, East Side, Hegewisch, Morgan Park, Mount Greenwood, Pullman, Riverdale, Roseland, South Deering, Washington Heights, West Pullman Near South: Auburn Gresham, Avalon Park, Chatham, Douglas, Englewood, Fuller Park, Grand Boulevard, Greater Grand Crossing, Hyde Park, Kenwood, Oakland, South Chicago, South Shore, Washington Park, West Englewood, Woodlawn North/Central: Edgewater, Lake View, Lincoln Park, Lincoln Square, Loop, Near North Side, Near South Side, North Center, Rogers Park, Uptown, West Ridge Northwest: Albany Park, Avondale, Belmont Cragin, Dunning, Edison Park, Forest Glen, Hermosa, Irving Park, Jefferson Park, Logan Square, Montclare, North Park, Norwood Park, O'Hare, Portage Park Southwest: Archer Heights, Armour Square, Ashburn, Bridgeport, Brighton Park, Chicago Lawn, Clearing, Gage Park, Garfield Ridge, McKinley Park, New City, West Elsdon, West Lawn West: Austin, East Garfield Park, Humboldt Park, North Lawndale, South Lawndale, Lower West Side, Near West Side, West Garfield Park, West Town ​​​​​This dataset is in a forma​​t for spatial datasets that is inherently tabular but allows for a map as a derived view.

Selected variables from the most recent 5 year ACS Community Survey (Released 2023) aggregated by Ward. Additional years will be added as they become available. The underlying algorithm to create the dataset calculates the percent of a census tract that falls within the boundaries of a given ward. Given that census tracts and ward boundaries are not aligned, these figures should be considered an estimate. Total Population in this Dataset: 2,649,803 Total Population of Chicago reported by ACS 2023: 2,664,452 % Difference: %-0.55 There are different approaches in common use for displaying Hispanic or Latino population counts. In this dataset, following the approach taken by the Census Bureau, a person who identifies as Hispanic or Latino will also be counted in the race category with which they identify. However, again following the Census Bureau data, there is also a column for White Not Hispanic or Latino. The City of Chicago is actively soliciting community input on how best to represent race, ethnicity, and related concepts in its data and policy. Every dataset, including this one, has a "Contact dataset owner" link in the Actions menu. You can use it to offer any input you wish to share or to indicate if you would be interested in participating in live discussions the City may host.

The Nature Conservancy created the Chicago and Cook County Greenprint to help identify where nature can help address the challenges that communities face from climate change, such as flooding, poor air quality, and excessive heat. We geared the Greenprint tool to be particularly sensitive to identifying those communities on the 'front lines' of climate change, where historic misdirection of resources and injustice have resulted in greater climate vulnerability.The Chicago Greenprint focuses on these three questions:What locations have the greatest need for tree canopy interventions based on urban heat impacts and air quality issues?What locations have the greatest need for stormwater interventions?And what locations have the greatest combined need in terms of our mission, looking across areas of flooding, air quality, excess heat, urban biodiversity, and connecting people to nature?The Greenprint does this by analyzing numerous layers of data to show which Chicago and suburban neighborhoods are most at risk for these challenges, as well as where there are opportunities for natural interventions like planting more trees or investing in green stormwater infrastructure. All of the data sources are publicly available, and were supplied by a range of governmental agencies and other partners, including the Chicago Metropolitan Agency for Planning, the Morton Arboretum, and the University of Chicago.These maps can be used by communities and other stakeholders to understand the risks they face and how nature can play a key role in solving threats posed by climate change. One important caveat for these maps is that areas that are unidentified can still have great need and opportunity for natural solutions to adapt to climate change. In particular, some environmental justice communities such as the East Side along the Calumet River are not highlighted in our analysis. This can happen because these areas are subject to cumulative impacts of a concentration of industries and legacy pollution that are not readily captured in this analysis. For this reason, it is helpful to supplement use of the Conservancy's Greenprint with other tools.

Applications to the Chicago Department of Transportation for permits under its jurisdiction where the work type is "Filming." These permits typically are permits to block or otherwise affect public streets in some way. Because all permits start as applications, this dataset also serves as a list of permits granted.

To assist communities in identifying racially/ethnically-concentrated areas of poverty (R/ECAPs), HUD has developed a census tract-based definition of R/ECAPs. The definition involves a racial/ethnic concentration threshold and a poverty test. The racial/ethnic concentration threshold is straightforward: R/ECAPs must have a non-white population of 50 percent or more. Regarding the poverty threshold, Wilson (1980) defines neighborhoods of extreme poverty as census tracts with 40 percent or more of individuals living at or below the poverty line. Because overall poverty levels are substantially lower in many parts of the country, HUD supplements this with an alternate criterion. Thus, a neighborhood can be a R/ECAP if it has a poverty rate that exceeds 40% or is three or more times the average tract poverty rate for the metropolitan/micropolitan area, whichever threshold is lower. Census tracts with this extreme poverty that satisfy the racial/ethnic concentration threshold are deemed R/ECAPs. This translates into the following equation: Where i represents census tracts, () is the metropolitan/micropolitan (CBSA) mean tract poverty rate, is the ith tract poverty rate, () is the non-Hispanic white population in tract i, and Pop is the population in tract i.While this definition of R/ECAP works well for tracts in CBSAs, place outside of these geographies are unlikely to have racial or ethnic concentrations as high as 50 percent. In these areas, the racial/ethnic concentration threshold is set at 20 percent.
