From the press release:
New food hardship data from the Food Research and Action Center (FRAC) show continuing struggles with hunger for millions throughout 2011, as nearly one in five Americans said there were times they didn’t have enough money to buy food that they or their families needed.
FRAC’s food hardship report (pdf) analyzes data that were collected by Gallup and provided to FRAC. The data were gathered as part of the Gallup-Healthways Well-Being Index project, which has been interviewing almost 1,000 households daily since January 2008. FRAC has analyzed responses to the question: “Have there been times in the past twelve months when you did not have enough money to buy food that you or your family needed?” The report contains data throughout 2011 for every state, region, congressional district, and 100 of the country’s largest metropolitan areas (MSA). Gallup asked the question of 352,789 households in 2011.
