What is the key purpose of calculating the Aggregate Ratio?

Calculating the Aggregate Ratio is crucial for evaluating the fairness of property assessments. This ratio provides a way to compare the assessed values of properties to their actual market values, helping assessors identify potential disparities or biases in property assessments. By understanding how well the assessments reflect the true market conditions, officials can ensure that the property tax burden is distributed equitably among taxpayers. This analysis can lead to adjustments in assessment practices or further investigations into specific areas that may be over- or under-assessed, ensuring fairness in taxation.

The other options address different aspects of real estate and market analysis but do not capture the primary focus of the Aggregate Ratio. For example, assessing total sales prices relates more to market trends rather than assessment fairness. Similarly, determining average property size or measuring total income from sales involves different calculations and objectives not aligned with the goal of ensuring equitable property assessments.
