Usage Guidance

  • This metric is intended to capture the average household size of clients who were recipients of the organization's products or services. This metric may be reported in conjunction with Client Households: Total (PI7954) and its various submetrics.
  • Organizations that provide products and services that are used by an entire household (clean cookstoves, home weatherization, etc.) might find it more appropriate to report on the number of client households served rather than the number of the client individuals. By multiplying the number of Client Households by the Client Household Size, organizations can get an estimate of 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 process. Organizations can refer to the following sources for additional information on determining client household sizes, in addition to national census information:
