Privacy-Safe Aggregation Standard (k-Anonymity): Exact street addresses, parcel numbers, coordinates, and homeowner identities are strictly protected and never shown on this map. Statistics are calculated only for zones meeting a minimum threshold of 1 verified properties. Zones with fewer than 1 submissions are suppressed to prevent re-identification.
⚠️
Data Coverage & Sample Size Notice: Understanding self-selected datasets: The figures on this map reflect verified community submissions only — not a certified citywide audit. Mean vs. weighted aggregate: A simple average of percentage increases can differ from the true aggregate assessment change because higher-value parcels contribute more total dollars to the tax base. Do not conflate ward averages with the city's reported 69% aggregate valuation growth.
