How do influenza and pneumonia death rates vary across states?

Influenza and pneumonia mortality data from the CDC WONDER database tracks deaths classified under ICD-10 code J09-J18 across all US states and territories. In 2017, this cause accounted for 55,672 deaths nationally.

The 20.0-point spread between the highest-rate state (Hawaii, 29.6/100K) and the lowest (Florida, 9.6/100K) reflects significant geographic variation. Age-adjusted rates use the year 2000 US standard population, enabling fair comparison between states with different demographic profiles. States above the national average of 14.9 per 100,000 may face higher risk factors related to healthcare access, environmental conditions, or socioeconomic disparities.

What the 2017 Influenza and pneumonia Record Shows

In 2017, CDC WONDER classified 55,672 deaths under ICD-10 code J09-J18 (Influenza and pneumonia) across 51 US states and territories, with age-adjusted rates ranging from 9.6 per 100,000 in Florida to 29.6 per 100,000 in Hawaii - a 20.0-point spread. The national average settled at 14.9 per 100,000 with a median of 14.0, and the 3.1x gap between extremes reflects how influenza and pneumonia mortality concentrates geographically rather than distributing evenly across the population.

The top-rate cluster, led by Hawaii, Mississippi, Tennessee - typically shares a recognizable pattern: higher prevalence of upstream risk factors, limited preventive-care infrastructure in rural areas, and uneven specialist access. The bottom-rate cluster - Florida, Vermont, Minnesota - tends to combine broader insurance coverage, stronger primary-care networks, and earlier detection pathways. Because rates are age-adjusted to the year 2000 US standard population, the gap is not an artifact of older populations in higher-rate states, it reflects real differences in underlying exposure, healthcare delivery, and socioeconomic conditions that persist across the 19-year CDC WONDER record (1999–2017).

For researchers, public-health planners, and individual readers, the practical read of the 2017 Influenza and pneumonia record is comparative: states above the 14.9 national average face elevated mortality burden relative to the country overall, while those below it show better outcomes on this specific cause, though a single-cause ranking does not capture a state's total health picture. These figures describe population-level mortality rates from a specific ICD-10 classification 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.

Frequently Asked Questions

How many people die from influenza and pneumonia each year in the US?
In 2017, 55,672 deaths were attributed to influenza and pneumonia across all 51 US states and territories, with an average age-adjusted rate of 14.9 per 100,000 population.
Which state has the highest influenza and pneumonia death rate?
Hawaii has the highest age-adjusted death rate for influenza and pneumonia at 29.6 per 100,000 population (2017), with 637 total deaths.
Which state has the lowest influenza and pneumonia death rate?
Florida has the lowest age-adjusted death rate for influenza and pneumonia at 9.6 per 100,000 population (2017), with 3,057 total deaths.
What is the age-adjusted death rate and why does it matter?
The age-adjusted death rate accounts for differences in age distribution between states, making it possible to compare influenza and pneumonia mortality fairly. Without age adjustment, states with older populations would appear to have higher death rates simply due to demographics rather than actual health differences.
How wide is the gap between the highest and lowest influenza and pneumonia death rates?
The gap between the highest rate (Hawaii, 29.6/100K) and lowest rate (Florida, 9.6/100K) is 20.0 per 100,000, a 3.1x difference. This variation reflects differences in access to care, lifestyle factors, environmental conditions, and public health investment.
What years of influenza and pneumonia data are available?
Mortality data for Influenza and pneumonia is available from 1999 to 2017, covering 19 years of CDC WONDER data across all US states and territories.

What the influenza and pneumonia data shows

Hawaii carries the heaviest influenza and pneumonia burden - 3.1× the age-adjusted rate of Florida. Read the geography and the age adjustment together before drawing conclusions.

Age-adjusted rates use the 2000 U.S. standard population for fair cross-state comparison; figures are population statistics, not individual risk.
