The figure for the estimated housing shortage across the world according to the internationally recommended standards, (PPD 3.5) is 428,700,000 units. However this figure is more than double if it is calculated using the dutch standards (PPD 2.4); 1,088,219,000 units.
The above diagram considers the housing shortages and surplus in countries around the world. The diagram is taken from the magazine Volume 21:The Block
When considering the world housing shortage it is important to also consider the number of people living in inadequate conditions around the world. A UN figure in 2001 estimated a world slum population of 923,986,000.
Dwelling: a dwelling is a room or suite of rooms and its accessories in a permanent building or structural separated part thereof, and is intended for private inhabitation.
Household: A household includes all the persons who occupy a housing unit.
PPD: The PPD is obtained by dividing the national population by the total dwelling count. This can be interpreted as an indicator of the housing shortage. The higher the indicator value, the worse the housing conditions are.
