Household food insecurity, moderate or severe hunger

(The following description comes from the source organization.)
The model for household food security status levels is adopted from the United States model of food security status levels published by the United States Department of Agriculture in 2000. Food insecurity is based on a set of 18 questions and indicates whether households both with and without children were able to afford the food they needed in the previous 12 months. Questions related to food security focused on all members of the household and not just the main respondent to the survey. Thus a respondent is classified based on the level of food insecurity present in the household which may not be necessarily that felt by the respondent.
