The following table provides an overview of the distribution of the permanent resident population in Summit County. These population numbers are based on U.S. Census data and annual population estimates prepared by the State Demography Office in the Colorado Division of Local Government.

2The 2019 population is based on the most recent population estimates published by the State Demographer.

Approximately 52% of the permanent residents in the county live in unincorporated areas (properties located outside of town boundaries). The County's Snake River Basin has become the most populated of the unincorporated areas, primarily due to the increased permanent resident population in the Summit Cove and Dillon Valley neighborhoods (currently the two largest and most densely populated neighborhoods in unincorporated Summit County). Among the incorporated towns, the permanent resident population of Breckenridge increased most dramatically from 2000-2010; however, Silverthorne's permanent resident population has increased the most significantly since 2010.
The most recent population estimate released by the State Demographer indicates that, as of July 2019, the permanent resident population of Summit County was 30,983. This represents an 11% increase in permanent residents from the 2010 Census. The State Demography Office estimates population in arrears as of July 1 of each year (e.g., the 2020 population estimate will be released by the State Demographer in July of 2021).
