Definition: Residential connections x (Average household size or Household multiplier)

Rationale: This indicator measures the number of people that could potentially benefit from the distribution of the IFI intervention. Data for 'residential connections' can be obtained from the client while data for ‘average household size’ varies by country and can be obtained from UN Demographic Yearbook data, which provides population size and total number of households for each country. If such data is not available, IFIs may instead use IFC’s ‘household multiplier’, which is standardized across countries. The conversion methodology may have the potential to be equally applicable to other sectors such as gas or water sector.
