Disaggregates another metric in terms of client income. For example, Client Individuals (PI4060) disaggregated by this metric would yield the number of clients with increased, decreased, or no change in income. See usage guidance for further information.
Report all:
Organizations should footnote all assumptions used, including source of disaggregation, as well as method for gathering related data (e.g., survey to a sample set of clients, survey to all clients, data gathered as part of client intake form). Organizations should disclose whether clients are reporting changes in pre- or post-tax income and ensure consistency across samples and reporting periods.
This disaggregation, applied to another metric, is intended to capture the share of that metric which applies to each selected category of change in client income. Organizations should obtain this data by asking clients whether their income has increased a lot (double or more), increased a little (less than double), decreased, or stayed the same during the reporting period. Organizations should report the number of clients in each category: large increase, small increase, decrease, and no change in income.
Organizations may report both the total number of clients per category (e.g., total number of clients with a large increase, small increase, decrease, and no change in income) and the proportion or percentage in each category compared to the total number of clients.
In specific contexts, and based on evidence, this metric may serve as a proxy indicator of whether the outcome being sought by an investor or organization is occurring (the WHAT dimension of impact). 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.
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).
