Definition: Estimated percentage of adults with and without adverse childhood experiences (ACEs) before age 18, by presence of children ages 0-17 in the household and number of ACEs (e.g., in 2011-2017, among Alameda County adults ages 18 and older living in households with children, 13% had been exposed to four or more ACEs).
Data Source: UC Davis Violence Prevention Research Program, tabulation of data from the California Behavioral Risk Factor Surveillance System and American Community Survey (Apr. 2020).
Footnote: This indicator reports on eight adverse childhood experiences: (1) household member was mentally ill, (2) household member abused alcohol or drugs, (3) household member was sentenced to serve time in jail or prison, (4) parents were separated or divorced, (5) witnessed domestic violence in the home, (6) experienced physical abuse at home, (7) experienced verbal abuse at home, (8) experienced sexual abuse. The notation S refers to data that have been suppressed because the 95% credible interval—a Bayesian counterpart to a confidence interval—was wider than 20 percentage points. For more on the Bayesian methodology used in analyzing these data, see (Chen et al., 2014) and (Song et al., 2016).
