What the 2017 Illinois Mortality Record Shows
Across 10 tracked cause-of-death categories, CDC WONDER logged 80,704 deaths in Illinois during 2017. Heart disease led with 25,394 deaths (163.3 per 100,000, age-adjusted), putting the state at #22 of 51 states for this cause, where a higher rank corresponds to a higher rate nationally. The five biggest causes account for 67,315 deaths, or 83.4% of the state total.
Illinois's average age-adjusted rate across all tracked causes was 53.1 per 100,000 - 4% below the national average of 55.5. A below-national rate like this one is a favorable aggregate read, but aggregate numbers can hide a cause or two running above benchmark even while the overall picture looks good. Over the 1999–2017 window, total deaths decreased by 6.6%, and the state-wide average age-adjusted rate declined by 26.7%.
How to read this record & data notes
For planners, clinicians, and individual readers, the practical read of the 2017 Illinois 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.
