Household-level targeting risk

Privacy

Targeting resolved down to a single-household granularity (e.g. one residential parcel or a cell containing exactly one dwelling) functions as individually addressable targeting even when labeled as 'neighborhood' targeting.

Detection

Target cell/geography contains a single residential structure or a household count of 1 per census/parcel data.

Mitigation

Enforce a minimum household count per targetable unit, coarsen automatically if below threshold
Reject or flag targeting requests whose resolved geography maps to a single dwelling
