Indicator: Incidence of child maltreatment (including physical, psychological, neglect, etc.) per 1,000 children
Description: Substantiation Rates for a given year are computed by dividing the unduplicated count of children with a child maltreatment substantiation by the child population and then multiplying by 1,000. For more information, see: http://cssr.berkeley.edu/ucb_childwelfare/RefRates.aspx
Data Limitations: http://cssr.berkeley.edu/cwscmsreports/methodologies/default.aspx?definition=allegDetail&backReport=RefRates&report=
Some investigations for child maltreatment may not close by the end of the year. The data source for a year goes up to the end of June 30 in the following year, which allows for an additional six months of time to close investigations. The rate should not increase significantly after this. However, indicator updates prior to this period should be considered preliminary as the rate may increase after the data source is closed.

Indicator Source Changes: As of Quarter 4, 2014, the 2010-2015 child population data—the denominators for these rates—have been updated with revised projections (December 2014) from the California Department of Finance. As a result, there may be differences in rates for these years when compared with those published previously.
