The Kem C. Gardner Policy Institute prepares subcounty population estimates to support informed decision making in Utah. Here we share annual housing and population estimates for cities and census tract areas in Salt Lake County and Utah County from 2010 to 2017. We produced these results using the housing unit method, one of the most widely used estimation methods for detailed geographic levels. Refer to the research links for the full research report and downloadable dataset. The visualizations below can also be used to explore tract and city-level results.
