Grand Lake, Colorado demographics

Grand Lake, CO demographics: median age 61.4; 35.2% of adults 25+ hold a bachelor’s degree. Age, race, households, languages and education, ACS 2020–2024 with margins of error.

Grand Lake has 402 residents. Below 1,000, most survey estimates on this page have wide margins of error, so this detail page is kept for reference but not offered to search engines. The main Grand Lake profile summarizes the measures that can be compared reliably.

ACS 2020–2024 · Grand Lake town, Colorado · Incorporated town · GEOID 0831715. The survey estimates a population of 333 for its five-year window. This is separate from the annual July 2025 population estimate on the city overview.

Median age in Grand Lake is 61.4 years, with a 90% margin of error of 2.3 years. There are 198 households (±71). 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.

A family household contains related people under the Census definition. A nonfamily household can contain one person or unrelated people sharing a home. 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.
