I have a question regarding All Mortality Incidence estimates. I am working in the US setup (BenMAP Version 1.5) and have a user-defined grid of census block groups within a 4-county area. My model inputs for baseline PM2.5, control PM2.5, and population data all have 2,647 row-column combinations (which represent 2,647 census block groups in my grid). The population data is an output from the PopGrid program and I have included the _popwgt file in my population dataset to show what percentage of each census block group falls within each county. I have double checked that the row-column combinations for these inputs match the row-column attributes from the shapefile I used to define my grid domain.
As shown below, my air quality delta also populates all 2,467 census block groups:
However, when I run the EPA Standard health impact functions for PM2.5 (based on the BenMAP 2030 mortality incidence dataset), incidence data is shown for all but about 200 of the census block groups defined in my grid domain (this is true for all the standard PM2.5 HIFs, regardless of age groups represented). A small portion of these domains that are missing incidence data are explained by having zero population or no delta, but about 160 have both population (for the age groups specified in the HIFs) and nonzero baseline-control model data.
What are some possible reasons that I would get no incidence data (point estimates) in my health impact results for certain row-column combinations in my user-defined grid? These row-column combinations aren’t even shown as having zero values in the health impact results data table, they are just omitted altogether.
