Client Household Size (PI4548)

This metric is intended to capture the average household size of clients who received the organization's products or services during the reporting period. This metric may be reported in conjunction with Client Households: Total (PI7954) and its associated submetrics.

Organizations that provide products and services that are used by an entire household (such as clean cookstoves or home weatherization) might find it more appropriate to report on the number of client households served rather than the number of client individuals. By multiplying the number of Client Households by Client Household Size, organizations can estimate the number of individuals served. For example, an organization that sells products to 100 Client Households with a Client Household Size of 5 could estimate that they served 500 individuals.

Organizations that rely on assumptions to report against this metric should footnote all assumptions used in the calculation. Organizations can refer to the following sources for additional information on determining client household sizes, in addition to national census information:
