- Definition: Estimated percentage of children ages 0-17 with and without adverse childhood experiences (ACEs), by number (e.g., in 2016-2019, 13.5% of children in Alameda County had experienced two or more ACEs).
- Data Source: Population Reference Bureau, analysis of data from the National Survey of Children's Health and the American Community Survey (Jan. 2021).
- Footnote: Due to changes in methodology, these estimates should not be compared with data from earlier years. This indicator reports on nine adverse childhood experiences: (1) experienced economic hardship, (2) parent or guardian got divorced or separated, (3) parent or guardian died, (4) parent or guardian served time in jail, (5) witnessed domestic violence, (6) witnessed or experienced neighborhood violence, (7) household member was mentally ill, (8) household member abused alcohol or drugs, (9) treated unfairly because of race/ethnicity. Data are based on methods of local area estimation using the National Survey of Children's Health (NSCH) and American Community Survey. Data patterns across local areas may not align with direct NSCH estimates for California and the U.S.
- Measures of Childhood Adversity and Resilience on Kidsdata.org
Childhood adversity and resilience measures on kidsdata.org originate from three separate data sources and provide a rich and conceptually-related perspective on childhood adversity. Taken together, they present a broad framework to look at child adversity across the lifespan and provide useful data to inform and facilitate interventions. However, due to differences in methodology, data from the three sources should not be compared. The data sources are:Each of these data sources produces at least one overall index of childhood adversity. An overall index should be viewed as a more comprehensive measure than any of its individual items because it captures the cumulative magnitude of experiencing hardships.
NSCH data are collected by the U.S. Census Bureau on behalf of the Maternal and Child Health Bureau of the Department of Health and Human Services. NSCH uses a set of family, economic, and community adversity indicators to ask parents about current adverse experiences to which their children (ages 0 to 17) have been exposed. This is the most direct population-based survey measure of adversity among California children because it asks parents about the trauma their children have experienced while they are still children, compared with more traditional methods of asking adults to recall their childhood experiences.
MIHA is a collaborative effort of the Maternal, Child and Adolescent Health Division and the Women, Infant and Children Division of the California Department of Public Health and the Center on Social Disparities in Health at UC San Francisco. MIHA surveys postpartum women (ages 15 and older) who deliver a live birth about their own childhood hardships prior to age 14.
The BRFSS ACEs Module is adapted from the Adverse Childhood Experiences (ACEs) study by Kaiser Permanente and the Centers for Disease Control and Prevention. The data presented here were prepared by the UC Davis Violence Prevention Research Program, with support from the California Department of Public Health and the Public Health Survey Research Program at CSU Sacramento. They are based on adult recollections of their childhood experiences during the first 17 years of life and thus do not provide direct information about the current status of California's children.
NSCH, MIHA, and BRFSS data together provide a comprehensive framework for understanding and addressing child adversity across the lifespan. Among these three data sources, NSCH indicators are the most contemporary because they tap into parents' views of their children's current experiences. MIHA adds an intergenerational perspective by providing information about childhood hardships experienced by mothers of newborns. BRFSS provides a well-established standard measure of adult retrospective reports of adverse childhood experiences. Both NSCH and MIHA include a wider range of potentially adverse experiences, such as exposure to extreme poverty, community violence, and food and housing insecurity, whereas BRFSS focuses primarily on family dysfunction. Each source provides a unique but conceptually-related perspective on childhood adversity.

- Why This Topic Is Important
Childhood adversity—such as child abuse, exposure to violence, family alcohol or drug abuse, and poverty—can have negative, long-term impacts on health and well being (1, 2). Nearly half of U.S. children have experienced at least one adverse childhood event (3, 4). Early experiences affect brain structure and function, which provide the foundation for learning, emotional development, behavior, and health (5). The toxic stress associated with traumatic, and often cumulative, early adverse experiences can disrupt healthy development and lead to behavioral, emotional, school, and health problems during childhood and adolescence (2, 3, 4, 6). It also can lead to serious behavioral, emotional, and health issues in adulthood, such as chronic diseases, obesity, alcohol and other substance abuse, and depression (1, 2, 4). The more traumatic and toxic events experienced by a child, the more likely the impact will be substantial and long-lasting (7).
Resilience, an adaptive response to hardship, can mitigate the effects of adverse childhood experiences (3, 6, 8). It is a process of adapting well in the face of adversity, trauma, threats, or other significant sources of stress. Resilience involves a combination of internal and external factors. Internally, it involves behaviors, thoughts, and actions that anyone can learn and develop. Resilience is also strengthened by having safe, stable, nurturing relationships and environments within and outside the family (6, 8, 9).For more information on childhood adversity and resilience, see kidsdata.org’s Research & Links section.

- How Children Are Faring
Childhood adversity is common among California children, and many children experience multiple adverse circumstances or events that can pose a lifelong threat to their well being. The most timely assessment of childhood adversity comes from the National Survey of Children's Health (NSCH), in which parents report on the current status of their children. NSCH estimates from 2016-2019 show that 36% of California children ages 0-17 had been exposed to one or more adverse childhood experiences (ACEs), and around 4% had been exposed to four or more. At the local level, the share of children with two or more adverse experiences ranged from fewer than 1 in 8 (12%) to more than 1 in 4 (29%) across regions with data. Statewide and nationally, African American/black children were more likely than their Hispanic/Latino and white peers to have two or more ACEs in 2016-2019.
According to the 2013-2014 Maternal and Infant Health Assessment, one in four California women with a recent birth (25%) experienced two or more childhood hardships before age 14. Among young mothers ages 15-19, one-third (33%) experienced two or more hardship as children, compared with fewer than one-fifth (19%) of mothers ages 35 and older. Statewide, an estimated 34% of postpartum women living at or below the federal poverty guideline were exposed to at least two childhood hardships, more than double the estimate (16%) for women with higher family incomes (above 200% of the federal poverty guideline).
The California Behavioral Risk Factor Surveillance System ACEs Module, combining data from 2011 to 2017, shows that among California adults living in households with children, an estimated 17% experienced at least four ACEs before age 18.
- Policy Implications
In recent years, policymakers, researchers, and advocates increasingly have focused on childhood adversity (e.g., physical or emotional abuse, chronic neglect, caregiver substance abuse or mental illness, exposure to violence, and/or the accumulated burdens of family economic hardship), recognizing that such experiences can have harmful, lifelong consequences (1, 2). For example, children exposed to multiple adverse childhood experiences (ACEs) are more likely to develop negative health behaviors and chronic diseases in adulthood (1). Unaddressed ACEs place strain on public systems, including child welfare, education, health care, and juvenile justice (1). Policymakers have a role in helping to prevent ACEs, as well as in ensuring early identification and intervention for parents and children affected by trauma. While California has made strides in these areas, continued efforts are needed to ensure that all families have the opportunity to help their children thrive and reach their full potential (1, 3).
Policy and program options to help prevent, interrupt, and mitigate the effects of childhood adversity include:
For more information related to ACEs and resilience, see kidsdata.org’s Research & Links section or visit ACEs Connection, Center for Youth Wellness, and Prevention Institute. Also see Policy Implications in kidsdata.org’s Child and Youth Safety and Emotional and Behavioral Health topics.
- Raising public awareness about ACEs and their negative, lasting effects on children and families (1)
- Ensuring effective prevention services are in place, including strength-based parenting education, family support, and home-visiting services for families in need (4)
- Promoting policies that help reduce family stress and increase stability for children, e.g., policies to improve the social safety net for families in need, support family-friendly business practices, and ensure quality child care is affordable and accessible (4)
- Institutionalizing trauma-informed policies and practices for public and private systems and organizations (designed specifically to address the consequences of trauma and facilitate resilience and healing), including screening and intervention with reimbursement mechanisms (1, 3)
- Supporting formal workforce education about ACEs and trauma-informed approaches for professionals who work with families and children, such as administrators, doctors, nurses, educators, social workers, and juvenile justice staff (1, 3)
- Promoting increased collaboration across organizations and systems (e.g., local and state government, education, health care, juvenile justice, child welfare, and nonprofits) to address systemic barriers to preventing or treating trauma and toxic stress, including improving service coordination, sharing data, and aligning measures of success (1, 4)
- Supporting ongoing strategies to provide accessible, culturally competent, trauma informed, and resilience-building systems of mental health, substance abuse treatment, and other community services (1, 3, 5)
- Expanding data collection related to ACEs and resilience to study and advance effective interventions aimed at preventing and reducing the impacts of trauma on children, families, organizations, systems, and communities (1, 3)
