County Level Regressivity Statistics
Select a county from the list to see a map of tract-level assessment levels.
Note: Sale ratios are normalized relative to the county’s median ratio in the year of sale. Counties where data is available for only one census tract are excluded from this visualization. In most U.S. counties, properties are assessed by a single office or under a uniform set of rules. However, in some places, notably New York State outside New York City, properties in a single county may be assessed under more than one set of rules, which can produce variations that are not necessarily inequitable. In California, taxable value is based on actual sale prices. The inequities there are products not of inaccurate assessment but of differences in the tenure of ownership.
