The IADC recognizes that not all data sources measure data at the individual person level, but rather the geographic level. Through a robust geocoding infrastructure, individuals within the clinical data sources accessible through the IADC can be linked to geographic or neighborhood level measures from disparate data sources.
This capability has been used to link individuals defined in a clinical cohort to census tract (or other geographically relevant areas) measures from the American Community Survey, Polis Center’s SAVI, or other relevant data source.
