The Median Multiple is used to indicate the affordability of housing in any given community.[1] The Median Multiple is widely used for evaluating urban markets, and has been recommended by the World Bank.[2][3]

The Median Multiple is the ratio of the median house price by the median gross [before tax] annual household income. This measure has historically hovered around a value of 3 or less, but in recent years has risen dramatically, especially in markets with severe public policy constraints on land and development.[4]


The International Housing Affordability Survey uses the following table to determine affordability ratings:[5]

Rating Median Multiple
Severely Unaffordable 5.1 & Over
Seriously Unaffordable 4.1 to 5.0
Moderately Unaffordable 3.1 to 4.0
Affordable 3.0 & Under
