Counting notes

One row is a license event, not necessarily one dog.

The city export does not contain a dog ID, license/emblem ID, or anonymized owner ID. Renewals can therefore repeat the same dog, while two different dogs can share the same name and traits.

What “registry profile” means: a distinct combination of dog name, breed, color, gender, ZIP code, and ward. That removes obvious repeated rows and gives a steadier popularity signal, but it can still merge different dogs or split one dog after a move or profile change. We publish both the 147,119 license-event rows and the 116,813 registry profiles, and never describe either as an exact count of unique Chicago dogs.
