In seven California counties, more than 22% of children have been diagnosed with asthma at some point in their lives, according to 2011-2012 parental report data newly posted on In addition to variation in prevalence, there is variation in asthma outcomes like hospitalizations. Statewide, the 2012 asthma hospitalization rate for children ages 0-17 was 11.7 per 10,000 individuals, but county rates varied, ranging from 5.1 to as high as 30.6 per 10,000.
