These estimates translate into roughly 605 million, 260 million and 688 million children under age 15, respectively. The relationship between food insecurity and poverty, and well-being varies by region, demonstrating that definitions of food insecurity depend on regional context, and encompass more than monetary poverty alone. Finally, correlations of food insecurity and income per capita between 2006 and 2015, show that some regions were harder hit by the shocks in food prices and the Great Recession than others. In addition, further research on how food insecurity differs between children and adults will be important for future efforts to address and reduce child hunger.
