“How Do Experiential Food Security Measures Respond to Shocks:
Evidence from the Gallup World Poll”

Experiential food security measures are becoming more popular given their versatility and low cost to collect, but it is unclear whether biases in these subjective measures affect their ability to estimate underlying wellbeing. Given the growing emphasis on such measures in tracking the nutrition-related Sustainable Development Goals, it is important to better understand how they compare to more traditional measures, like calories and dietary diversity, which can be more expensive to collect. Previous research has found that dietary diversity is more sensitive to shocks than calories. We examine the sensitivity of experiential measures from the Gallup Food Insecurity Experience Scale to regional temperature and precipitation shocks, which serve as a proxy for exogenous income shocks for rural households. The individual-level data from 2014 cover over 150 countries, with at least 1000 individuals in each country. We find that less severe indicators of experiential food security (e.g., poor diet quality) are more responsive to shocks than more severe indicators (e.g., skipping meals), similar to the traditional measures. This evidence suggests that the low-cost experiential measure data could be useful in the rapid monitoring of food security.
Anna D’Souza holds a PhD and MS in Economics from the University of California, Los Angeles and a BS in Economics and Finance from New York University. She specializes in research concerning food and nutrition security, shocks and household coping mechanisms, conflict, governance, and international trade. Her work can be found in leading development and agricultural economics journals such as Economic Development and Cultural Change, World Development, Journal of Development Economics, the American Journal of Agricultural Economics, and Food Policy, as well as BMJ Global Health, the Journal of Development Studies, Economic Governance, and the Ethiopian Journal of Economics.
