Falling long-run death count

What this means: National influenza and pneumonia deaths fell -13% from 1999 to 2017. Even lower-rate causes still show a wide state spread.

Hawaii leads at 29.6/100K; Florida is lowest at 9.6/100K (3.1x gap).

Source: CDC WONDER, Underlying Cause of Death (CDC NCHS / NVSS), 2017. Age-adjusted rates allow fair comparison across states.

Influenza and pneumonia in the lower-rate third

In 2017, CDC WONDER attributed 55,672 deaths to influenza and pneumonia (ICD-10 J09-J18). Mean state age-adjusted rate 14.9/100K places this cause in the lower-rate third of the leading-cause set.

The 20.0-point spread across 51 jurisdictions is age-adjusted to the year 2000 US standard population, so the gap between Hawaii and Florida is not an artifact of older populations alone. Chronic-disease gaps usually track upstream risk, preventive care access, and specialist reach rather than one shared treatment story.

National influenza and pneumonia deaths fell -13% from 1999 to 2017. Long-run national deaths are down 13% from 1999 to 2017; a falling count can still leave high-rate states above the cause average. These figures describe population-level mortality under ICD-10 J09-J18 and are not individual risk advice.

30 states plotted by total influenza and pneumonia deaths against the age-adjusted rate per 100,000. Total deaths and the age-adjusted rate are only weakly related here (r=-0.15) -- a state's raw death count is driven largely by its size, not necessarily by an elevated per-capita risk, and vice versa.
