This dashboard was made in order to visualize possible correlations between lead risk and pollution burden percentiles vs low birth weight percentiles. The data was pulled from the CES 4.0 database, which is a publicly available database summarizing environmental health exposures in California. For the purpose of this dashboard, the data is grouped and summarized by the approximate location variable, which is closely tied to the city the data was collected. Version 4.0 of this database was released in 2021.
The first visual is an interactive map of California, with the 767 unique “Approximate Locations” each having its own point on the map with the relevant variables labeled.
The two graphs in the white column are interactive scatter plots with either Lead Risk or Pollution Burden plotted vs low birth weight percentiles. We see that higher lead risk seems to be more correlated to low birth weight but the plots have pretty poor clustering around the regression lines.
This map will show the census tracts along with the three percentiles of interest: average pollution burden, lead risk among children in the neighborhood, and then low birth weight percentile for the area. Please note that 227 observations were excluded from the map due to not reporting low birth weight percentiles.
