ZIP Code Tabulation Area (ZCTA)
Definition
A statistical geographic area created by the Census Bureau that roughly corresponds to USPS ZIP codes. ZCTAs are built from census blocks and designed to approximate ZIP code delivery areas.
Why It Matters
ZCTAs allow demographic data to be analyzed at the ZIP code level, which is how most people think about their neighborhood. They enable fine-grained analysis of income, education, and housing patterns.
How It's Measured
The Census Bureau assigns census blocks to ZCTAs based on the most frequent ZIP code in each block. There are approximately 33,000 ZCTAs nationwide.
