3. Children who have health insurance for the entire yearIncludes the percentage of children, ages 0–17, who have health insurance for the entire year, as a percentage of all children. County-level estimates are based on California Health Interview Survey (CHIS). To create multi-year estimates, Children Now conducted analysis of race/ethnicity data using “askCHIS”, and combined 2011–2014 data (July 2016). CHIS clusters responses into three multi-county groups for select low-population counties. The multi-county groups are as follows: (1) Del Norte, Siskiyou, Lassen, Trinity, Modoc, Plumas and Sierra; (2) Tehama, Glenn and Colusa; (3) Tuolumne, Calaveras, Amador, Inyo, Mariposa, Mono and Alpine.

NA (Not Available)Data that are not available are noted as NA. The most frequent reasons for NAs include the unavailability of longitudinal data, fewer than 10 cases (low number events), and statistically unstable estimates.

Asterisks*An asterisk indicates that data should be interpreted with caution. Asterisks were used to note low number of events (fewer than 10) or unstable data with large confidence intervals. Data or estimates with low numbers and large confidence intervals indicate that a data point may not be a true representation of the larger population.
