Data were collected for the Benin Comprehensive Food Security and Vulnerability Analysis (CFSVA) in February and March 2013. The analysis was based on two surveys – a household-level survey of 15,000 households and a key informants survey of 750 villages. Results are reliable at national, department and commune levels and they are indicative of the situation in the pre-lean season period. Nationally, 1,1 million people were found to be food insecure (representing 11% of all households). A third of households (34%) were classified as being marginally food secure. The departments of Couffo, Mono, and Atacora had the highest prevalence of food insecurity (more than 25% each). Within departments, food insecurity was found to be unevenly spread; indeed, in some specific communes more than 40% of households were classified as food insecure.
