Number of unique very poor individuals who were clients of the organization during the reporting period.
Organizations should footnote all assumptions used, including source of data, as well as details on the assessment tools used to identify clients’ poverty level. See usage guidance for further information.
This metric is intended to capture the number of unique very poor clients who received the organization's products or services during the reporting period. It is not a measure of foot traffic, nor is it intended to capture the number of consumer transactions. For example, a customer who makes two purchases during a period should be counted only once. Organizations wishing to report on total client transactions should refer to Client Transactions (PI5184).
Because assessing the poverty level of stakeholders is complex, organizations will likely use specific assessment tools to accurately report on this metric. See the glossary definition for additional information on commonly used tools to help determine the absolute poverty level of individuals and households.
This metric is intended to capture the unique number of specific individuals served. Organizations should not use any household multipliers when reporting against this metric. If organizations consider entire households 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 using direct data. For example, organizations that sell solar lanterns through a series of local network distributors might estimate the number of client individuals reached based on the number of units sold. Organizations should footnote details on how and why these assumptions were made.
For healthcare providers, “client individuals” refers to patients. For housing providers, “client individuals” refers to residents or tenants.
This metric is multi-dimensional with regard to the five dimensions of impact. It may help describe the WHO dimension when the stakeholder group represented by the metric is the stakeholder group targeted by the investment or organization. It may also help measure the HOW MUCH Scale dimension, which helps estimate the number of the targeted stakeholders experiencing the outcome. For more on the alignment of IRIS metrics to the five dimensions of impact, see IRIS+ and the Five Dimensions of Impact (https://iris.thegiin.org/document/iris-and-the-five-dimensions/). No single metric is sufficient to understand an impact; rather, metrics are selected as a set across all dimensions of impact. When possible, the selection of metrics to measure and describe the five dimensions should be based on best practice and evidence.
This is a submetric of Client Individuals: Total (PI4060), which has 17 other related submetrics.
Metrics identified as "cross-category" are those that are relevant to any IRIS+ Impact Category or Impact Theme (i.e., these metrics are not specific to any particular industry/category or theme).

IRIS Metrics Work Better in Sets
To use IRIS metrics—and the resulting data—to understand impact performance, IRIS metrics should be used and analyzed in generally accepted sets and according to well-defined objectives. IRIS+ gives you access to generally accepted Core Metrics Sets aligned to common Impact Themes and Sustainable Development Goals (SDGs).
