Early studies of child endangerment examined the demographic characteristics of the individual parents and children. Later research models studied the geo-structural demographics of the environment, and although useful information resulted, there was room for over interpretation of findings. Recently a second view of the social environment has emerged which accounts for peer, parental and broader community social influences in conjunction with the geo-structure. This paper reviews these models of understanding child endangerment and analyzes multiple public domain data sources, relating to alcohol and drug use, through epidemiological mapping. Findings suggest a "nesting" effect of four levels of interaction which create and support either risk or protective factors.
