Using Geospatial Methods in Childhood Lead Poisoning Prevention Programs

In this paper, we explore how the construction and analysis of geographically referenced data can improve outcomes for children at risk of lead exposure. We discuss the history of how children were identified for lead testing and lead intervention (both medical and housing) over time, as well as the shortcomings of the United States’ current approach. We then suggest ways that geospatial approaches can improve lead testing and intervention programs, especially in settings with limited information or financial resources.
