Sonoma County continues to be one of the healthiest counties in California, based on a new report released by the University of Wisconsin Population Health Institute and the Robert Wood Johnson Foundation.

This is the second year of the County Health Rankings, the most comprehensive report of its kind to rank the overall health of nearly every county in all 50 states by using standard measures to determine how healthy people are and how long they live, according to a recent news release from Sonoma County Health Services.

The rankings demonstrate where people live, learn, work and play influence how healthy they are and how long they live. In 2011, Sonoma County ranks 12th in California, and is in the top 10 percent when compared to national benchmarks in several important areas, such as adult obesity, preventable hospital stays and the ratio of population to primary care providers. But the rankings further identify areas for improvement. For example, despite the rich agricultural heritage of the Sonoma County, access to healthy foods continues to be a low health measure within the rankings.
