    About Colorado's IQ Ranking

    Colorado ranks #11, driven by its highly educated population — the state has one of the highest percentages of college-degree holders in the nation. Boulder and Denver attract tech workers, outdoor enthusiasts, and educated professionals. The state's aerospace, technology, and renewable energy sectors create demand for skilled workers, pulling in talent from across the country.

    What Shapes Colorado's Cognitive Profile

    Researchers call it the Colorado paradox: the state ranks near the top in adults holding bachelor's degrees yet near the middle in the share of its own high school graduates who eventually earn one. Imported talent does most of the work. Federal laboratories reinforce the effect, with NREL in Golden, NCAR and NIST in Boulder, and NOAA facilities employing thousands of physical scientists along the Front Range. The Colorado School of Mines posts some of the highest mid-career salary outcomes of any public university, reflecting demand from energy and aerospace employers like Lockheed Martin in Littleton and Ball Aerospace in Boulder. Meanwhile the TABOR amendment constrains tax revenue, leaving per-pupil K-12 spending below the national average despite the state's wealth, a mismatch unusual among high-attainment states. The San Luis Valley and the eastern plains post outcomes far from the Front Range norm. Estimated averages for Boulder County alone would rank among the highest recorded for any US county.
