Ratio of children within the area served by the organization who experienced stunting as of the end of the reporting period.
Organizations should footnote all assumptions used, including source of data.
This metric is intended to capture the prevalence of stunting among children in the region served by the organization. The World Health Organization (WHO) defines stunting as height less than two standard deviations from the median of the WHO's Child Growth Standards. Stunting often results from malnutrition and other factors correlated with poverty.
Sources for these data at the regional or national level include the WHO (https://www.who.int/nutrition/databases/en/) and USAID's Demographic and Health Surveys Program Database (https://dhsprogram.com/Data/).

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).
