The Voices of the Hungry project (VoH) aims to estimate prevalence of food insecurity consistently across national populations. These estimates are based on conditions and behaviors reported by adults through the Food Insecurity Experience Scale Survey Module (FIES-SM). The data collected are used to compute access to food and are adjusted to comparable international scales of food insecurity. The main purpose of the report is to allow food security analysts to evaluate the statistical soundness and adequacy of the methods described.
