The largest and most comprehensive study of hunger to date contains some stunning findings. As many as 27 million people, including 9 million children, get emergency food help each year from America's Second Harvest. About 36 percent of adults served are employed. Many families who experience food insecurity say they've had to choose between buying food and paying for their utilities, rent or mortgage, or medical care. Food pantries and emergency service organizations rely heavily on volunteers to get their work done.
