Occurring throughout the world, lack of proper nutrition is both a consequence and cause of poverty. Impoverished individuals are less likely to have access to nutritious food and to escape from poverty than those who have healthy diets. Disparities in socioeconomic status, both between and within nations, provide the largest threat to child nutrition in industrialized nations, where social inequality is on the rise. According to UNICEF, children living in the poorest households are twice as likely to be underweight as those in the richest. Those in the lowest wealth quintile and whose mothers have the least education demonstrate the highest rates of child mortality and stunting. Throughout the developing world, socioeconomic inequality in childhood malnutrition is more severe than in upper income brackets, regardless of the general rate of malnutrition.
