Education and Employment Data by ZIP Code
This guide is part of the ZIP Code Demographics learning library, written by our editorial team to help readers use ZIP-level Census data accurately. It explains ZIP code education and employment data in plain language, with the same care we apply to the data pages themselves: no invented figures, no borrowed statistics, and a clear line between what the Census Bureau publishes and what it does not.
How educational attainment is measured
The ACS asks adults about the highest level of schooling completed. ZIP Code Demographics summarizes the distribution with one headline figure: the share of residents age 25 and over who hold a bachelor's degree or higher, combining the published counts for bachelor's, master's, professional and doctoral degrees and dividing by the published total for the age-25-and-over population. Age 25 is the standard base because most people have finished formal education by then; including younger adults would understate attainment in college towns and overstate it nowhere.
Why the degree share matters so much
Of all the figures in a ZIP profile, the bachelor's-plus share correlates most strongly with the others: with median income, with home values, and with the industry mix of local jobs. It is also one of the more stable ACS measures in small areas, because it changes slowly. A ZCTA whose degree share runs far above its state is usually tied to a university, a professional employment center or a commuter belt serving one; a share far below usually signals an industrial, agricultural or retirement profile. The figure describes residents, note — not the jobs physically located in the ZIP area, which the ACS does not measure.
Employment: three rates, three meanings
Our profiles publish three labor figures, all for residents age 16 and over. The employment share is the employed fraction of that whole population. Labor-force participation adds the unemployed who are actively looking, showing how much of the population is engaged with work at all — a rate that falls naturally in older ZCTAs. The unemployment rate divides the unemployed by the civilian labor force only, matching the concept behind headline national unemployment, though the ACS five-year version is a period average rather than a monthly reading and will not match current Bureau of Labor Statistics releases.
Reading the two sections together
Education and employment repay joint reading. High degree share with middling employment share often means students or early retirees; modest degree share with high employment and participation often means strong demand for skilled trades and logistics labor. Because the ACS covers 2020–2024 in the current vintage, ZIP profiles also carry the imprint of the pandemic period — remote-work migration lifted degree shares and incomes in many suburban and exurban ZCTAs, a pattern visible across the largest-ZIP profiles on this site.
