About This Dataset
Delaware (DE) has 138 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 Wilmington and Dover to rural and suburban areas across Delaware's Mid-Atlantic geography.
Delaware the most corporate-domiciled state relative to its size. This makes accurate, ZIP-level data especially valuable for businesses and researchers focused on business expansion 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 Delaware's rural areas.
Flood zone classifications come from the FEMA National Flood Hazard Layer (NFHL). Each Delaware 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 Delaware.
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 Delaware, broadband availability varies significantly between urban ZIP codes in Wilmington 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 Delaware for grant applications and community health planning.
