Assessors use something called a “Coefficient of Dispersion” to measure the quality of assessments.
It’s something like the margin of error used in political polls.
The McHenry County Supervisor of Assessments has provided the following data from 2015. This is the most recent analysis available.
The lower the number, the more equal or uniform are the assessments.
Compare the results for each township with the County’s 19.30% Coefficient of Dispersion.
As one can see, the most uniform assessments are in Grafton Township, where Al Zielinski is Assessor and the margin of error is 11.5%.
Next best is Algonquin Township, where retiring Bob Kunz is Assessor. His margin of error is 15.15%.
You will note that generally the higher a township’s population, the more uniform the assessments.
