Haiti is the top country by depth of the food deficit in the world. As of 2016, depth of the food deficit in Haiti was 546 that accounts for 4.95 % of the world's depth of the food deficit. The top 5 countries (others are Zambia, Central African Republic, Democratic People's Republic of Korea, and Namibia) account for 18.12 % of it. The world's total depth of the food deficit was estimated at 11,031 in 2016.
The depth of the food deficit indicates how many calories would be needed to lift the undernourished from their status, everything else being constant. The average intensity of food deprivation of the undernourished, estimated as the difference between the average dietary energy requirement and the average dietary energy consumption of the undernourished population (food-deprived), is multiplied by the number of undernourished to provide an estimate of the total food deficit in the country, which is then normalized by the total population.
