Sedalia, Colorado Demographics & Population 2026

A note before these figures: with a population of 37, Sedalia'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.

Population Overview

Sedalia is a small community located in Colorado, within Douglas County. The total population is 37. It ranks as the 450th most populous out of 472 Census-designated places in Colorado.

Economy, Income & Housing

The ACS records no residents below the poverty line in Sedalia. 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. The survey records no unemployed residents in Sedalia, which reflects the size of the sample rather than a labor market without joblessness. 100.0% of occupied housing units are owner-occupied. This homeownership rate is 51% higher than the state average of 66.2%.

Race & Ethnicity

Every resident counted in Sedalia was recorded as White (non-Hispanic). A figure of exactly 100.0% reflects a survey sample too small to capture the community's full composition rather than a precise measurement.

Education

0.0% of residents aged 25 and older hold a bachelor's degree or higher. This is among the lowest rates in the state, which may correlate with employment and income patterns. Nationally, 35.7% of adults hold at least a bachelor's degree. 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.
