The number and rate per 1,000 of children under age 18 entering the foster care system. Some states allow children to remain in the foster care system until their 18th birthday while other states have age limits that extend a few years beyond this. To allow for comparison across states, this indicator includes the population under age 18 in foster care. Children are categorized as entering foster care if they have a valid date for entry into care during a particular fiscal year. Rates are based on Census Bureau estimates of the population of children ages 0 to 17 in each state, as of July 1st of the respective year. National estimates do not include Puerto Rico.
