Summit, Utah Demographics & Population 2026

A note before these figures: with a population of 104, Summit's ACS estimates come from a small number of survey responses and carry wide margins of error. Individual percentages below — particularly rates that round to 0% or 100% — are approximations, not precise measurements. See data.census.gov for the published margins of error.

Economy, Income & Housing

The ACS records no residents below the poverty line in Summit. In a community this small the estimate rests on very few survey responses, so it should be read as an absence of measurement rather than a measured absence of poverty.

No surveyed resident aged 25 or older reported leaving school before earning a high school diploma, though a rate of exactly 100% reflects the limits of a small sample. Notably, 18.0% of adults hold a graduate or professional degree, indicating a highly educated workforce.

Data Sources & Methodology
