What is the Coefficient of Dispersion (COD)?
Coefficient of Dispersion (COD), as it relates to real estate assessments, is a statistic that measures how consistent property assessments are within a group.
“a statistical measure of variation of individual assessment ratios around the median level of assessments. An average error expressed as a percent of the median; an indicator of assessment uniformity found by dividing the average deviation by the median. It is the most common method used in measuring assessment uniformity.” – State of Illinois PTAX 1-E Introduction to Sales Ratio Studies
Why is COD important?
COD is important because it helps ensure that property taxes are fairly distributed among taxpayers.

“There are strong incentives to encourage chief county assessment officers to equalize assessments. The state pays one-half of the salary of each supervisor of assessments if the DOR determines the total assessed value of the real property of the county, as equalized by the supervisor of assessments, is between 31⅓ and 35⅓ percent of the total fair cash value of the property. (35 ILCS 200/3-40) Also, state law provides a $3,000 bonus from the state to any assessor in a county of less than 3 million whose jurisdiction has a median level of assessment between 31⅓ percent and 35⅓ percent and a variance among properties (coefficient of dispersion) within certain limits. In counties of less than 50,000 inhabitants, the coefficient of dispersion can be no more than 30 percent, and in counties larger than 50,000 no more than 15 percent. (35 ILCS 200/4-20) A low coefficient of dispersion is an indication of equity among the assessments in a jurisdiction.” – Page 16
