I am working on identifying factors contributing to fecal contamination. we have our location of interest. We want to know the total count of the human population from the 1 km radius buffer zone around each area. I know the procedures in ArcGIS Pro (creating buffer zone and clipping population layer).

My problem is I failed to search for a proper GIS layer carrying population data that will clip population counts only within the buffer zone. I downloaded GIS layers from the online portal, NHGIS, and some other sources, but they clip all the data that is even outside of the zone. What I am doing wrong here? And how could I find a proper Population GIS data file?

I work on ArcGIS Pro.

  • Welcome to GIS SE. As a new user, please take the Tour. Population experts get ulcers when folks try to disaggregate their data (because doing so invalidates their work). Please Edit the Question to detail the exact procedure you are using, so we can evaluate what could be wrong.

    Are you sure that you are using a 1km buffer and not a 1 degree buffer?

  • I am using 1 km buffer. I think I am not using proper gis layer.
