Median Proportion (Proportion médiane)

The median proportion is an indicator of the general level of values entered on the assessment roll of a municipality. Established after the filing of the assessment roll, the median proportion is the central tendency of a distribution of individual proportions. It connects the selling prices of properties that have been subject of real estate transactions with their assessment as entered on the current assessment roll. The measured proportion is considered as representative of the general level of the roll and, therefore, should be the tendency for each of the values that are entered.
