I have socioeconomic status (SES) data of every health authority (HA) in the province. I overlay a watershed boundary polygon on top of multiple HAs and would like to know: What is the SES of the population residing within the watershed?
I am using ArcGIS desktop 10.5. So far I have tried converting HAs to points and then rasterizing it so that I can use the zonal statistics tool to summarize all cells within the watershed. However, this does not account for the fact that people are not homogeneously distributed in space and there is no way of knowing how accurate the conversion was (this is where I am stuck).
