This report shows the average number of people living in Vermont households. Multiple-person households can include married or cohabitating people, children, relatives and also roommates. 

This report uses data from the United States Census Bureau’s American Community Survey (ACS), an ongoing, national survey. The ACS replaces the Decennial Census “long form” and is now the only source for Census Bureau data on topics such as ancestry, educational attainment, income, spoken languages, migration, disability, employment, and housing features.

Vermont Insights uses 5-year ACS estimates to increase the reliability of the data for all geographic areas.

For more information on the ACS, including sampling and response rates for Vermont, see:

This report uses the census variable average household size.

Some considerations when using and interpreting the ACS data include:

ACS estimates represent the conditions that might have been present at any time within the estimate time period. ACS estimates should only be compared with like estimates. For example, 1-year data can only be compared with other 1-year data and cannot be compared with 3- or 5-year data.

If using the ACS for longitudinal analysis (comparisons over time), multi-year estimates should not overlap.
