County Groupings for 2005, 2007 & 2009 CHIS Data:
The California Health Interview Survey produced county-level results for 41 counties, and area-level results for the remaining 17 counties with smaller populations, which were analyzed collectively in groupings of 3 to 7 counties. These county groupings included: Grouping 1: Del Norte, Siskiyou, Lassen, Trinity, Modoc, Plumas, Sierra, Grouping 2: Tehama, Glenn, Colusa, and Grouping 3: Tuolumne, Calaveras, Amador, Inyo, Mariposa, Mono, Alpine. Although the percentages are listed for each individual county, those percentages for the 17 counties in area-level groupings reflect the outcomes for the entire area rather than for the single county.
County Groupings for 2001 & 2003 CHIS Data:
The California Health Interview Survey produced county-level results for 33 counties, and area-level results for the remaining 25 counties with smaller populations, which were analyzed collectively in groupings of 2 to 6 counties. These county groupings included: Group 1: Tuolumne, Calaveras, Amador, Inyo, Mariposa, Mono and Alpine; Group 2: Siskiyou, Lassen, Trinity and Modoc; Group 3: Humboldt and Del Norte; Group 4: Tehama, Glenn and Colusa; Group 5: Nevada, Plumas and Sierra; Group 6: Mendocino and Lake; Group 7: Sutter and Yuba; and Group 8: Monterey and San Benito. Although the percentages are listed for each individual county, those percentages for the 25 counties in area-level groupings reflect the outcomes for the entire area rather than for the single county.
Note: Maps use the natural break classification method, which reflects patterns
in the data by dividing the map into naturally occurring groups. Using statistical tools, this method
determines cut-off points for each group by identifying large gaps in data values.
