The interactive web map demonstrates a correlation between older homes and higher cases of elevated blood lead levels in children. Specifically, areas with a higher concentration of red and yellow shading, which represent neighborhoods with homes built in or before the 1940s and up to 1955 respectively, display a greater number of individual dots signifying affected children. This visual representation indicates that older homes are more likely to have lead-related health risks, allowing pediatricians and public health officials to target their lead screening initiatives in these communities.
