Grafton, North Dakota demographics

Grafton, ND demographics: median age 43.2; 16.7% of adults 25+ hold a bachelor’s degree. Age, race, households, languages and education, ACS 2020–2024 with margins of error.

ACS 2020–2024 · Grafton city, North Dakota · Incorporated city · GEOID 3831820. The survey estimates a population of 4,102 for its five-year window. This is separate from the annual July 2025 population estimate on the city overview.

Median age in Grafton is 43.2 years, with a 90% margin of error of 3.9 years. There are 1,851 households (±116). Age and household distributions show how these totals are composed; they do not establish which neighborhood suits a particular person.

Every count and share is an estimate. “±” is a 90% margin of error (MOE); pp means percentage points. Derived shares use the category count divided by the named universe. Aggregated category MOEs and percentage MOEs are approximate. A margin larger than half its estimate is flagged as low precision. Blank source uncertainty is shown as unavailable, never zero.

Households with children can also appear in the household-type and size tables, so those tables must not be added together. Household estimates exclude people living in group quarters from the household universe.

Foreign born means not a U.S. citizen at birth; it includes naturalized citizens. Language categories describe speech at home among people age five and older. A language other than English at home does not establish that someone cannot speak English. This city page uses the published C16001 summary categories because the more detailed B16001 table does not provide these city records in this release.

These are respondents’ residence patterns one year before their survey response, pooled across the five-year window. They are not a net migration count for 2025. A person can move to a different house within the same city or county; moves within the same county should not automatically be interpreted as new arrivals to the city.

Health insurance, internet access and veterans

10.7% of Grafton residents (±3.3 percentage points) had no health insurance coverage when surveyed, compared with 6.5% in North Dakota and 8.4% nationally. 80.6% of households subscribe to broadband of any type, including cellular data plans.
