GIS Maps of Childhood Lead Poisoning

Geographic Information System (GIS) maps showing the association of locations where children have been found to be lead poisoned and the proportion of housing built before 1950, are available upon request at the county and city levels in different formats and with different datasets. The overlap between the red dots and  dark brown shaded areas represents the relation between homes built before 1950 and children who were lead poisoned. These maps are available on request by contacting the Wisconsin Childhood Lead Poisoning Prevention Program, 608-266-5817.

Wisconsin County Maps (1996 - 2001)

Maps with 3 views are available for every county in Wisconsin and cities with a population of 20,000 or greater. The blood lead data represented in these maps is for children under the age of six tested from 1995 to 2001.

Map 1 - The top left-hand map shows different shaded areas with each shade representing the percentage of houses built prior to 1950. The greater the percent of houses built prior to 1950, the darker the shading. Houses built prior to 1950 in Wisconsin have a high probability of containing paint with a high concentration of lead. If the paint is in poor condition it poses a serious threat to children’s health.

Map 2 - The bottom left-hand map shows the locations of children who have been tested for lead poisoning over the period of 1995-2001.

Map 3 - The larger right-hand map indicates the locations of children who have been lead poisoned (a blood lead level of greater than or equal to 10 micrograms per deciliter).

Select Wisconsin City Maps (1996 - 2006)

Maps with two views are available for select Wisconsin Cities, those with a population of 20,000 or greater. The blood lead data represented in the maps is for children under the age of six tested from 1996 to 2006.

Map 1 - The top left-hand map shows different shaded areas with each shade representing the percentage of houses built prior to 1950. The greater the percent of houses built prior to 1950, the darker the shading. Houses built prior to 1950 in Wisconsin have a high probability of containing paint with a high concentration of lead. If the paint is in poor condition it poses a serious threat to children’s health.

Map 2 - The larger right-hand map indicates the locations of children who have been lead poisoned (a blood lead level of greater than or equal to 10 micrograms per deciliter).
