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.

Ward precincts, which function as local election districts to determine the polling places for voters, based on their addresses. Precincts are based on U.S. Census Bureau blocks. These precincts were first used for the 2014 elections and first used for Chicago municipal elections in 2015.

The Historical Urban Ecological (HUE) data project was created for exploring and analyzing the urban health environments of seven major United States cities - Baltimore, Boston, Brooklyn, Chicago, Cincinnati, Manhattan, and Philidelphia - from 1830 through 1930. The data for each city includes ward boundary changes, street networks, and ward-level data on disease, mortality, crime, and other variables reported by municipal departments. The HUE data set was produced for the "Early Indicators of Later Work Levels, Disease and Death" project, funded by the National Institute of Aging. This collection represents the GIS data for each of the seven American cities, and in addition to ward boundary changes and street networks, includes in-street sewer and water sanitation systems coverage. All cities except Cincinnati include sanitation infrastructure data, and for Baltimore only water infrastructure is available. The city of Chicago includes supplemental GIS layers which reflect a reconstruction of two of Homer Hoyt's maps of average land value (1933 dollars) in the City of Chicago for 1873 and 1892. The square mile areas defined by Hoyt using Chicago's system of mile streets have been fit to the HUE street centerlines for Chicago. The Excel data tables include information about deaths in each ward broken down by cause of death, age, race, gender, as well as information about live births and deliveries.

As discussed in http://bit.ly/wardpost, the City of Chicago changed to a new ward map on 5/18/2015, affecting some datasets. This ZIP file contains CSV exports from 5/15/2015 of all datasets except Crimes - 2001 to present. Due to size limitations, that CSV is at https://data.cityofchicago.org/d/5wdx-rdkp. These CSV files contain the final or close-to-final versions of the datasets with the previous ("2003") ward values.

In association with the July/August 2022 process for 43rd ward residents to apply for the opportunity to fill the aldermanic vacancy in that ward, residents were also invited to fill out an online survey, seeking their opinions on issues. The results of that survey are shown in this dataset.

Respondents were presented with eight issues plus "other" and asked to rank each one as being between Not a Priority (1) and Urgent Priority (5). There was no limit to how often each ranking could be used, although respondents were encouraged to rank only a few issues as Urgent Priority.

The final question was free text, intended to capture descriptions of "other" issues but if the respondent provided other text, it is included except in limited cases where it is redacted for privacy or similar reasons.

Please note that the survey is not and was not intended to be a random sample or otherwise scientifically or statistically valid. There were no formal barriers to people not residents of the 43rd ward responding, people responding more than once, or other things of that nature. It was intended only as a simple tool to collect such information as people cared to submit and should be interpreted in that spirit.

A copy of the original survey is at https://www.chicago.gov/content/dam/city/about/wards/ward-43-application-processs/Survey.pdf.
