In some jurisdictions, when it is necessary to correct inequalities in state wide tax assessments, an' equalization' factor is used to achieve uniformity. An equalization factor may be applied to raise or lower assessments in a particular district or county. The assessed value of each property in the area is multiplied by the equalization factor, and the tax rate is then applied to the equalized assessment.
