Incidentally, if you're wondering "How does one define 'food security'?", you administer surveys, score them, and compare the scores to threshholds. For example, here is a 9 question survey for children: http://www.ers.usda.gov/media/476115/youth2006.pdf http://www.ers.usda.gov/media/476115/youth2006.pdf Typical question: "[In the last 30 days, d]id your meals only include a few kinds of cheap foods because your family was running out of money to buy food?" Choices are "A lot", "Sometimes", "Never." Score 1 point if the answer isn't Never. If you score 2+ points on this out of 9, you're food insecure. This is how you get headlines like "1 in 6 Americans doesn't know where their next meal is coming from."
