.. ZIP Code 2023 ACS Data Profiles: Demographic, Social, Economic, Housing .. use with Visual Data Analytics (VDA) Geographic Information Systems (GIS) The primary purpose of using the ZIP Code ZCTA project is to provide mapping and related support for the demographic-economic estimates. For example, development of a view of 2023 America Community Survey percent high school graduates or median household income. Use the data contained in the Demographic, Social, Economic, Housing layers described in detail by the metadata files. Understanding ZIP Codes vs ZCTAs It is important to distinguish between ZIP Codes and ZIP Code Tabulation Areas (ZCTAs): ZIP Codes (USPS) • Used by USPS for mail delivery as lines, not polygons. • Often dual-sided (each side of a street may belong to a different area). • No official ZIP Code area polygons or shapefiles are produced by the USPS or other agencies. ZCTAs (Census Bureau) • Polygonal areas developed by the U.S. Census Bureau for data tabulation. • Emulate ZIP Codes, based on respondent data. • Not all areas have mail delivery; ZCTAs do not cover the entire U.S. • Data for ZCTAs are tabulated from the Census, ACS, and other programs. • Developed once per decade. • Approximately 33,171 ZCTAs, compared to about 44,000 ZIP Codes. • ZCTAs do not include P.O. Boxes or FPO military codes; accounting for difference. Using the ZIP Code ZCTA VDA GIS Project To find a ZIP Code/ZCTA: 1. Enter the 5-digit ZIP Code in the iVDA interactive mapping search bar and press Enter. 2. The map view will relocate to the corresponding ZIP Code/ZCTA. 3. Enter your own ZIP Code to explore the data. Use the ZIP Code ZCTA American Community Survey Data Profiles (ZIP_DP) GIS project using iVDA or VDA4.

Geographic data, also known as spatial or geospatial data, identifies the location of features on earth. GIS combines the visual elements of maps with the ability to link characteristics about those features in datasets. This relationship allows GIS to locate, display, analyze, and model data. GIS technology integrates geographic data with statistical and administrative data using statistical methods and analytics. These abilities make GIS valuable to a wide range of public and private enterprises for explaining events, predicting outcomes and planning strategies. And collaborating on those issues.
