Sources
Datasets draw on public records published by appraisal districts, cities, counties, special districts and state agencies. Each dataset page lists the exact documents used and the date each was accessed.
Method
Figures are copied from the source as published, without adjustment, unless the dataset page says otherwise. Where a calculation is made, such as a combined tax rate, the dataset page shows how it was done.
Updates
Datasets are refreshed yearly, after new rates or figures are certified. Each dataset page shows the period it covers and when it was last updated.
Boundaries
Neighborhood and district boundaries differ between sources. Each entry names the boundary source it uses.
Limits and reuse
Public records contain errors, and figures can change after publication. Check the original source before relying on a figure for a financial or legal decision. Reuse terms are stated on each dataset page.
