NOTE: Reports are updated with data through 2023 as of 12/30/2024. Over 300 additional counties (and equivalents) have been added and Alaska, Hawaii, and the District of Columbia are included for the first time. Additionally, Connecticut is now reported on the Regional Council level and not counties which are no longer used.
In order to compare the performance of many jurisdictions in a common format, the Center has utilized commercially available data provided by First American and CoreLogic, firms that collect local records from both public and private entities to provide a uniform picture of the market values, assessed values, and a range of descriptive information for more than 99% of all residential properties in America… almost 40 million sales in total.

What does this map show?
In all fifty states, lower-value homes were on average assessed at higher rates than higher-value homes.
As shown in our map, a value of 1 means that low and high value homes were on average assessed at the same rate. Values below 1 (shaded in reds and yellows) are regressive areas where lower value homes are assessed at higher rates than high value homes. For example, in the least equitable state (Alabama), low value homes are assessed at over twice the rate of high value homes on average. Property assessments are roughly converted into property taxes—so in Alabama these lower value homes likely pay a tax rate much higher that of high value homes.
