An important Integrated Food Security Phase Classification (IPC) component is the Acute Food Insecurity Reference Table for Household Group Classification (household reference table), which provides qualitative, graduated descriptions of five acute food insecurity phases, along with thresholds for key household-level outcome indicators that can be used to classify the severity of acute food insecurity. In this study, researchers examined the relationships among select household food consumption outcome indicators commonly used in acute IPC analyses. They recommend a series of changes to the indicators and thresholds used in the acute IPC household reference table to improve the overall quality of classifications of acute food insecurity severity.
