Usage Guidance

  • This metric is intended to capture the number of unique adolescent clients who were recipients of the organization's products or services during the reporting period. It is not a measure of foot traffic. It is also not intended to capture the number of consumer transactions. For example, a customer who makes two purchases during a period should only be counted once. Organizations wishing to report on total client transactions should refer to Client Transactions (PI5184).
  • Organizations operating in the health sector may find it beneficial to report with greater specificity on the ages of their clients and may choose to use best practice guidelines, such as those provided by the World Health Organization (WHO). Recommended WHO youth classifications include: infant (birth to 1 year), child (1 to 10 years), and adolescent (10 to 19 years). (
  • This metric is intended to capture the unique number of specific individuals serviced. Organizations should not use any household multipliers when reporting against this number. If organizations consider the entire household to be the customer/client, they can report against Client Households: Total (PI7954) and its associated submetrics.
  • Many organizations may not be able to report on the number of clients based on direct data. For example, organizations that sell solar lanterns via a series of local network distributors might estimate the number of client individuals reached by the number of units sold. Details on how and why these assumptions were made should be footnoted.
  • For healthcare providers, client individuals refers to patients.
