This dataset quantifies the dominant atmospheric pollutant within each census tract, providing a robust foundation for analyzing geographical disparities in respiratory health concerns.
<DIV STYLE="text-align:Left;"><P><SPAN><SPAN>The purpose of this dataset is to determine a temporally aggregated air quality index per census tract, establishing a comprehensive base for probing geographical inconsistencies in the concentrations of pollutants in these areas. It is developed to aid public health research and urban planning initiatives by enhancing our understanding of, and ability to address, local health and socioeconomic concerns. The dataset is curated from the EPA's EJScreen API, which temporally and spatially summarizes air quality data. Utilizing FME, a spatial intersection and summary within census tracts in Baltimore County was performed.</SPAN></SPAN></P></DIV>
