About This Dataset
Illinois (IL) has 1,386 ZIP Code Tabulation Areas (ZCTAs) as defined by the US Census Bureau. This dataset covers all of them — from high-density urban ZIP codes in Chicago and Aurora to rural and suburban areas across Illinois's Midwest geography.
Illinois Chicago's metro ZIP codes span one of the widest income ranges in the Midwest. This makes accurate, ZIP-level data especially valuable for businesses and researchers focused on franchise territory planning.
The demographic core of this dataset comes from the US Census Bureau's American Community Survey (ACS) 5-year estimates (2019–2023 vintage, published December 2024) — the gold standard for ZIP code-level statistics. The 5-year estimates pool five years of survey responses to produce reliable numbers even for small or low-population ZIP codes, which is especially important in Illinois's rural areas.
Flood zone classifications come from the FEMA National Flood Hazard Layer (NFHL). Each Illinois ZIP code is flagged for the percentage of its area falling within high-risk flood zones (Zone A, AE, V, and VE designations). This is particularly relevant for real estate, insurance, and lending decisions in Illinois.
Broadband coverage data comes from the FCC's National Broadband Map, which tracks the percentage of addresses in each ZIP code with access to fixed broadband service at 25/3 Mbps, 100/20 Mbps, and gigabit speeds. In Illinois, broadband availability varies significantly between urban ZIP codes in Chicago and rural areas.
Food desert designations come from the USDA Economic Research Service Food Access Research Atlas. A ZIP code is flagged as a food desert when it meets the USDA's combined criteria for low income and limited access to a supermarket. This data is commonly used in Illinois for grant applications and community health planning.
