What the 2017 Colorado Mortality Record Shows
Across 10 tracked cause-of-death categories, CDC WONDER logged 27,626 deaths in Colorado during 2017. Cancer led with 7,829 deaths (131.0 per 100,000, age-adjusted), putting the state at #49 of 51 states for this cause, where a higher rank corresponds to a higher rate nationally. The five biggest causes account for 22,518 deaths, or 81.5% of the state total.
Colorado's average age-adjusted rate across all tracked causes was 47.9 per 100,000 - 14% below the national average of 55.5. A below-average state-level rate indicates relatively better mortality outcomes in aggregate, though individual causes within the state may still exceed national benchmarks and warrant separate examination. Over the 1999–2017 window, total deaths increased by 34%, and the state-wide average age-adjusted rate declined by 22.0%.
How to read this record & data notes
For planners, clinicians, and individual readers, the practical read of the 2017 Colorado record is layered: the state-wide average frames overall burden, the top-causes ranking identifies where the mortality load concentrates, and the multi-year trend indicates whether conditions are improving or worsening. Because age-adjusted rates use the year 2000 US standard population, differences between states and across years are not driven by demographic aging alone, they reflect real variation in exposure, prevention, and care delivery. These figures describe population-level mortality statistics and are not a substitute for medical advice; individual risk depends on personal health history, behaviors, and access to care. Consult a qualified healthcare professional about diagnosis, treatment, or prevention decisions.
