2015 Land Use Inventory:This file is a digital geospatial Environmental Systems Research Institute (ESRI) ArcGIS version 10.x File Geodatabase Polygon Feature Class representing land use in the seven northeastern Illinois counties (Cook, DuPage, Kane, Kendall, Lake, McHenry and Will). Land use is identified to nearly 60 categories, and was created using county parcel GIS boundaries and Assessor data, along with color orthorectificed aerial photography captured in the spring of 2015. Land uses were assigned to parcels using a combination of automated and manual techniques, using a variety of reference data sets for land use identification and validation. This dataset is considered an update of the 2013 parcel-based Land Use Inventory, and the primary focus was on parcels whose assessment records or geometry had changed between 2013 - 2015, suggesting a change in land use. Parcels were then dissolved on common land uses (to the limits of PLS sections or assessor blocks); polygons were generated for “non-parcel” (water, right-of-way) areas and classified using automated processes, and extensive topological cleaning was necessary to minimize gap/overlap issues. NOTE: Land use polygons are based on county parcel boundaries; special care must be exercised when comparing these data to earlier (2005, 2001, 1990) Inventories, which relied on manual drafting of land use boundaries that would extend to road centerlines.Supporting documentation for CMAP's 2015 Land Use Inventory:2015 Land Use Inventory Classification Scheme: full description of all land use categories2015 Land Use Inventory Geodatabase Schema: description of LUI attributes and domains2015 Land Use Inventory MetadataLANDUSE lookup .csv table to support shapefile downloads.See also the Land Use Inventory page on the CMAP website.

This dataset contains white-tailed deer (Odocoileus virginianus) land cover utility score (deer LCU score) data for every TRS (township, range, and section), township-range, and county in Illinois, USA, based on annual National Land Cover Database (NLCD) data released for all years between 2000 and 2023. LCU data is provided in CSV files for each spatial scale, with TRS data split into 2 CSV files due to size limits. Rasters (TIF) showing all deer habitat in Illinois are also provided to show the location, quality, and quantity of deer habitat. A metadata file is also included for additional information.

These data are single-beam bathymetry points compiled in comma separated values (CSV) file format, generated from a hydrographic survey of the northern portion of Lake Calumet in Cook County, Illinois. Hydrographic data were collected July 18-19, 2023, using a single-beam echosounder (SBES) integrated with a Global Navigation Satellite System (GNSS) mounted on a marine survey vessel. Surface water elevation data were collected July 18 utilizing a single-base real-time kinematic (RTK)/GNSS unit. Bathymetric data points were collected as the vessel traversed the northern portions of the lake along overlapping survey lines. The SBES internally collected and stored the depth data from the echosounder and the horizontal and vertical position data of the vessel from the GNSS in real time. Data processing required specialized computer software to export bathymetry data from the raw data files. A Python script was written to calculate the lakebed elevations and identify outliers in the dataset. These data are provided in comma separated values (CSV) format as LakeCalumet_SBES_20230718.csv. Data points are stored as a series of x (longitude), y (latitude), and z (elevation or depth) points along with variable length records specific to the data transects.

The library patronage indicator measures the percentage of the total resident population served by each public library (the percentage of eligible residents that holds an unexpired library card). Ten public libraries and public library districts in Champaign County are included: the Champaign Public Library, the Homer Community Library, the Mahomet Public Library District, the Ogden Rose Public Library, the Philo Public Library District, the Rantoul Public Library, the St. Joseph Township-Swearingen Memorial Library, the Sidney Community Library, the Tolono Public Library District, and the Urbana Free Library. Public libraries often serve as community hubs and offer a number of educational and social opportunities and services for their population served. Registration for and maintenance of a library card is one way a resident can engage in recreation and other community involvement.

In 2021, five of the ten libraries analyzed had residential participation rates between 20 and 30 percent: Champaign Public Library, 27.57 percent; St. Joseph Township-Swearingen Memorial Library, 25.12 percent; Mahomet Public Library District, 22.38 percent; Tolono Public Library District, 21.82 percent; and the Philo Public Library District, 21.3 percent.

The libraries with the greatest percentage of the resident population with unexpired library cards were the Homer Community Library, at 38.96 percent, and the Urbana Free Library at 30 percent. The libraries with the smallest percentage of the resident population with unexpired library cards were the Sidney Community Library, 18.13 percent; Rantoul Public Library, 17.22 percent; and the Ogden Rose Public Library, at 13.85 percent.

All ten public libraries in Champaign County saw the percentage of their resident population with unexpired library cards decrease between 2015 and 2021. It is worth noting that many library buildings were closed during part of 2020 due to the COVID-19 pandemic, and that along with statewide stay-at-home orders may have deterred residents from renewing or obtaining library cards.

The release of the 2020 Census results in 2021 shows that the population in eight of the ten library districts decreased from 2010 to 2020. It is important to note that the population of a library district sometimes differs than the population of the municipality where it is located (e.g., Tolono).

The two library districts that saw a population increase in 2020 were the Champaign Public Library and Tolono Public Library District. However, the number of unexpired library cards in those districts decreased in 2021, so the decrease in the percentage of the population with library cards cannot be explained by population growth.

The two library districts that saw an increase in the percentage of the population with library cards from 2020 to 2021 are the Homer Community Library and Urbana Free Library. The number of unexpired library cards at the Homer Community Library increased from 2020 to 2021, which explains the percentage increase. However, the number of unexpired library cards at the Urbana Free Library decreased from 2020 to 2021, so the percentage increase is due to the library district’s population decrease.

Data was sourced from the Illinois Public Library Annual Report (IPLAR), an annual report from the Illinois State Library and Office of the Illinois Secretary of State. The population data included in the IPLAR dataset is sourced from the 2020 Census. To be consistent with the data source, we have also calculated the percentage of residents with library cards based on the number of cardholders divided by the total 2020 Census population.

The property crime rate indicator includes both the total number of property crime incidents per year in Champaign County, and the number of property crime incidents per 100,000 people per year in Champaign County. “Property crimes” are those counted in the following categories in the Illinois State Police’s annual Crime in Illinois report: Burglary, Theft (Larceny), Motor Vehicle Theft, and Arson. Like violent crime, property crime is also a major indicator of community safety.

The property crime data spans the same time period as the violent crime data: 1996 to 2021. The total number of offenses and rate per 100,000 population are both substantially lower as of 2021 than at the beginning of the study period in 1996. 2021 actually saw the lowest number of offenses and the lowest rate per 100,000 population in the study period. There are significantly more property crime offenses in Champaign County than violent crime incidents.

This data is sourced from the Illinois State Police’s annually released Crime in Illinois: Annual Uniform Crime Report, available on the Uniform Crime Report Index Offense Explorer.

Overall educational attainment measures the highest level of education attained by a given individual: for example, an individual counted in the percentage of the measured population with a master’s or professional degree can be assumed to also have a bachelor’s degree and a high school diploma, but they are not counted in the population percentages for those two categories. Overall educational attainment is the broadest education indicator available, providing information about the measured county population as a whole.

Only members of the population aged 25 and older are included in these educational attainment estimates, sourced from the U.S. Census Bureau American Community Survey (ACS).

Champaign County has high educational attainment: over 48 percent of the county's population aged 25 or older has a bachelor's degree or graduate or professional degree as their highest level of education. In comparison, the percentage of the population aged 25 or older in the United States and Illinois with a bachelor's degree in 2023 was 21.8% (+/-0.1) and 22.8% (+/-0.2), respectively. The population aged 25 or older in the U.S. and Illinois with a graduate or professional degree in 2022, respectively, was 14.3% (+/-0.1) and 15.5% (+/-0.2).

Educational attainment data was sourced from the U.S. Census Bureau’s American Community Survey 1-Year Estimates, which are released annually.

As with any datasets that are estimates rather than exact counts, it is important to take into account the margins of error (listed in the column beside each figure) when drawing conclusions from the data.

Due to the impact of the COVID-19 pandemic, instead of providing the standard 1-year data products, the Census Bureau released experimental estimates from the 1-year data in 2020. This includes a limited number of data tables for the nation, states, and the District of Columbia. The Census Bureau states that the 2020 ACS 1-year experimental tables use an experimental estimation methodology and should not be compared with other ACS data. For these reasons, and because data is not available for Champaign County, no data for 2020 is included in this Indicator.

For interested data users, the 2020 ACS 1-Year Experimental data release includes a dataset on Educational Attainment for the Population 25 Years and Over.
