title: Toward Improved Understanding of Food Security: A Methodological Examination Based in Rural South Africa.
abstract: Accurate measurement of household food security is essential to generate adequate information on the proportion of households experiencing food insecurity, especially in areas or regions vulnerable to food shortages and famine. This manuscript offers a methodological examination of three commonly used indicators of household food security - experience of hunger, dietary diversity, and coping strategies. Making use of data from the Agincourt Health and Demographic Surveillance Site in rural South Africa, we examine the association between the indicators themselves to improve understanding of the different insight offered by each food security "lens." We also examine how the choice of indicator shapes the profile of vulnerable households, with results suggesting that dietary diversity scores may not adequately capture broader food insecurity. Concluding discussion explores programmatic and policy implications as related to methodological choices.
