From 2000 to 2010, Imperial County demonstrated the greatest percentage reduction in age-adjusted death rate from 42.0 to 26.1, which represented a 37.9 percent improvement.

Refer to Table 4 (PDF), Table 5 (PDF), and Table 6 (PDF) for detailed counts of deaths, age-adjusted rates, and 95 percent confidence intervals by county of residence. Trend charts showing age-adjusted unintentional injury death rates by county are accessible through the links provided below. Regression analysis was not applicable for unintentional injuries, because of the data variability.
Forty-three counties exhibited rates that were reliable each year.
Fifteen counties had rates that were unreliable or had no events during one or more of the years studied. Graphs are provided for these counties. However, this information should be interpreted with caution.
