Overview of the Survey
The One Nutrition Coverage Survey (ONCS) is methods-focused population-based household survey designed to generate comprehensive data on the coverage of multi-sectoral nutrition interventions across the life stages.
Developed under the Data for Decision in Nutrition (DataDENT) initiative, ONCS aims to strengthen how countries measure nutrition intervention coverage and use data for policy and program decisions. The findings, tools, and methods from ONCS will support governments, researchers, and development partners in designing, implementing, adapting or replicating comprehensive nutrition intervention coverage surveys.
