At a Glance
- In 2007, influenza and pneumonia ranked as the 8th leading cause of death in California.
- The age-adjusted death rate for influenza and pneumonia per 100,000 California residents in 2007 was 18.8, which represents a 35.6 percent decrease from a rate of 29.2 in 2000.
- Blacks had the highest age-adjusted death rate for influenza and pneumonia, followed by Whites, Asians, and Hispanics during this period.
- Both female and male age-adjusted death rates for influenza and pneumonia significantly declined from 2000 through 2007.
- Influenza and Pneumonia deaths increased with age. Approximately 50 percent of all deaths occurred among California residents 85 and older; this increased to over 90 percent when measured from age 65.
- Out of the 32 California counties that had reliable age-adjusted rates for each study year, 20 counties showed a statistically significant decrease in their influenza and pneumonia rates, while 12 counties did not show any statistically significant change.
The graph below illustrates a decrease in the U.S. and California age-adjusted death rates from 2000 to 2007. Although the difference decreased over time, California age-adjusted death rates remained slightly higher than the national age-adjusted death rates during this period.
