The paper describes the databases collected under several USAID projects in sub-Saharan Africa, reviews the basic vulnerability assessment model used by the Famine Early Warning System (FEWS), and evaluates the relations between the mapping of vulnerability to the food insecurity determined by these data, and poverty mapping. Issues discussed are: an overview of the FEWS project and vulnerability assessments; vulnerability and poverty in the Demographic and Health Survey (DHS) data; results and discussion (aggregated DHS statistics by geographic zone; using multivariate analysis; DHS indicators summarized by subnational administrative units; spatial filtering technique); and conclusions and implications.
