High School Graduate (% of Over 25) by Zip Code (ZCTA5) — New Hampshire

NOTE: Gray indicates insufficient data or a suppressed estimate.

High school graduation rates across New Hampshire are generally high, with most zip codes in the southern and central portions of the state falling in the 90–100% range, reflected by the predominance of yellow and yellow-green shading. A notable cluster of lower graduation rates appears in the northern regions, particularly in the White Mountains area and parts of Coös County, where several zip codes dip into the 75–85% range as indicated by darker green and teal tones. The southeastern corner and suburban areas surrounding Concord and Nashua consistently achieve the highest rates, contrasting sharply with the more rural and economically disadvantaged northern tier.
