More people are moving to the Denver metro area, according to new estimates from the Census Bureau, fueling population growth and possibly your road rage.
By the numbers: The Denver-Aurora-Centennial metro area grew 1.2% between July 2020 and July 2023, with more than 35,000 new people calling the Mile High City region home.
- That's compared with a 1% population increase nationwide.

Yes, but: The metro area's growth rate pales in comparison to other major metros in the U.S., particularly in the South.
- Meanwhile, Denver County's population as a whole dipped 0.1%, as did populations in Boulder (-1.2%) and Jefferson (-1.2%) counties, census figures show.
- That's mostly on par with the trend from 2020 to 2022, when all three counties saw their populations dip 1% or less.
Zoom out: Between July 2020 and July 2023, the state's fastest-growing counties were also some of its smallest, including Custer (17.2%), San Juan (12.8%) and Elbert (9.9%), for a collective total of about 3,500 new people.
- Other notable counties that saw growth include Weld (8.4%), El Paso (1.6%), Mesa (2.4%) and Larimer (3%).
The other side: Colorado counties that saw the steepest drops in population were Jackson (-5.1%), Kiowa (-4.9%) and Pitkin (-4.1%), albeit they only lost about 850 people altogether.
The big picture: The country's top four fastest-growing metro areas over the past three years were all in Florida, with Provo, Utah, and Austin, Texas trailing just behind, according to new U.S. census figures.
- Unsurprisingly, the cost of living in those cities is lower than Denver's.
Between the lines: The data is part of the most recent release of the annual Population Estimates Program, which tracks population numbers between censuses.
- It uses administrative records and other sources to calculate annual changes in population and housing.
