Insight: Updated Subcounty Estimates Share City, Tract Population Changes

By: Natalie Young

Our recently released subcounty report provides annual population and housing estimates from 2010 to 2017 for every city and census tract in Salt Lake and Utah counties. Though we released tract estimates with our previous 2010 to 2016 release, the addition of the city level estimates is new this year.

In these counties, one particular region steals the show in terms of population growth. We’ve seen it before – it’s the growth core of southwestern Salt Lake County and northwestern Utah County. Herriman, Saratoga Springs, South Jordan, and Eagle Mountain are the top-growing cities, contributing nearly a third of the combined population growth in the two counties (2016 to 2017). These cities have grown by way of large single-family developments.

Areas outside this growth core, such as Vineyard, beg for our attention as well. Vineyard’s population continues to surge as the large “@Geneva” master planned community adds new housing around the clock. From 2016 to 2017, we estimate that Vineyard added nearly equal the amount of new residents as Salt Lake City added (about 2,500 people). Vineyard is still a little place, but it transforms every year.
