What the 2017 Missouri Mortality Record Shows

In 2017, CDC WONDER tallied 46,763 deaths in Missouri across 10 tracked cause-of-death categories. Heart disease led the record with 14,820 deaths at an age-adjusted rate of 191.1 per 100,000 — placing Missouri at #11 of 51 states for this cause, where a higher rank corresponds to a higher rate. The top five causes accounted for 38,666 deaths (82.7% of the state total), a concentration pattern consistent with national mortality profiles where a small number of chronic-disease categories dominate the annual record.

Missouri's average age-adjusted rate across all tracked causes was 61.7 per 100,000 — 11% above the national average of 55.5. An above-average state-level rate signals elevated mortality burden relative to the country overall, often correlating with a mix of chronic-disease prevalence, healthcare access gaps, smoking and obesity rates, and socioeconomic factors that vary by region. Over the 1999–2017 window, total deaths increased by 2.9%, and the state-wide average age-adjusted rate declined by 19.5% — a directional signal that integrates population growth, aging demographics, and shifts in disease patterns across the CDC WONDER record. Neighboring-state comparisons in the table above provide regional context, since states sharing geography often share environmental, economic, and healthcare-delivery conditions that drive correlated mortality patterns.

For planners, clinicians, and individual readers, the practical read of the 2017 Missouri 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.
