The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. One such measure was the Antonucci Map. It was administered to subjects in Cohorts 3, 6, 9, and 12 and provided information regarding the subject's close friendships.

The Chicago Region Trees Initiative (CRTI) uses data including surface temperature, canopy cover, vulnerable populations, flooding, and air quality to identify where tree work will have the biggest impact. This story maps displays these layers and shows how CRTI combines them and uses the product to do targeted work.DOI: 10.5281/zenodo.5528672

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.

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.

OUTDATED. See the current data at https://data.cityofchicago.org/d/kjav-iyuj -- Special Service Areas (SSA) boundaries in Chicago. The Special Service Area program is a mechanism used to fund expanded services and programs through a localized property tax levy within contiguous industrial, commercial and residential areas. The enhanced services and programs are in addition to services and programs currently provided through the city. SSA-funded projects could include, but are not limited to, security services, area marketing and advertising assistance, promotional activities such as parades and festivals, or any variety of small scale capital improvements that could be supported through a modest property tax levy.

In 1969, Clifford Shaw and Henry D. McKay released the second edition of Juvenile delinquency and urban areas. Their book conducts statistical analysis, without the benefit of computers, on the impact of various socio-economic issues on juvenile delinquency in Chicago, Philadelphia, Boston, Cleveland, Cincinnati, and Richmond. Chicago is the major focus of the research with analysis exploring three time periods within the city 1900 to 1906, 1917 to 1923, and 1927 to 1933. The suburbs are also analyzed from 1934 to 1966. The book contains a number of maps with the rates of delinquency and socio-economic factors divided into “square mile areas”. These are explained by Shaw and McKay (see page 29 footnote 5) as “the basic units the city of Chicago was divided for the presentation of rates of delinquency and other data”. The rate data from 1927 to 1938 is divided into140 ‘square mile areas’ (which in many cases are more than a square mile in area).
