The PoU reflects the level of undernourishment from the point of energy intake in calories for measuring regular food access, whereas the Prevalence of Severe Food Insecurity (PoSFI), as an experience-based measure, allows for the measurement of the severity of the food insecurity condition at household and individual levels. Therefore, in addition to the PoU, indicators of prevalence of moderate to severe food insecurity (PoMSFI) are used and collected through surveys, as per FIES methodology. According to the latest estimates in 2015-2017,2.1 percent of the total population in the ECA region has been exposed to food insecurity at a severe level (PoSFI). This prevalence in the ECA region is much lower than the world average, which was 9.2 percent during the same period. This coincides with a gradual increase in the PoU (Figure 2). More in-depth studies will be needed to investigate the causes of the recent increase observed.
