"Early childhood risks" are markers of early childhood experiences that extensive research has shown to be detrimental to later academic and behavioral outcomes. In Philadelphia, evidence indicates that seven early childhood risks tracked by public agencies have negative effects on early school outcomes. These risks include low birthweight or preterm birth, inadequate prenatal care, teen mother, low maternal education, homelessness, lead exposure, and child maltreatment. The purpose of this research was to understand the early risk experiences of the entire population of children age 5 years in Philadelphia between 2008 and 2012. The specific questions were: (1) What are the prevalence rates of known early childhood risks, including low birthweight or preterm birth, inadequate prenatal care, teen mother, low maternal education, homelessness, lead exposure, and child maltreatment?; (2) What percentage of young children experienced multiple early childhood risks?; and (3) What is the geographic distribution of children experiencing multiple early childhood risks in Philadelphia? The Data Management Office (DMO) in the City of Philadelphia's Office for Health and Opportunity partnered with the Penn Child Research Center at the University of Pennsylvania's Graduate School of Education to create a data model that tracks evidence-based early risk experiences for children 0 to 5 years old. One table and three figures are appended.
