Hi
Having thought about this I would suggest (assuming this is a manual process)
- Add a new field to your "people" layer to hold the "Y" / "N" value. It would be a string field with a length of 1
- For each Buffer make a note of the Buffer ID and select the Buffer
- Use the Select By Location tool to select those "peoples' locations" that are inside of the Buffer.
- Use the Select by Attribute tool to create an attribute query to select those features in the "peoples' locations" layer which match the ID of the Buffer. Make sure the Selection Type is set to "Select subset from the Current Selection".
This will select only those locations which are within the Buffer and which match the Buffer ID.
5. Use the Field Calculator tool on to populate the newly created field of the selected records with a value of "Y"
I think this may be what you want to do...
I hope this helps
