It must be true, I read it in the American Community Survey (as reported by the Alaska Dispatch): "According to the survey, 9.9 percent of Alaska households fell below their respective poverty thresholds in 2010, putting the state in an effective statistical tie for second-lowest with Connecticut, Maryland, and New Jersey. New Hampshire's rate was found lowest, at 8.3 percent. Mississippi's was highest, at 22.4 percent."
More on poverty from the Alaska Economic Overview: "Alaska is a high-cost place to live, which can be especially challenging for those who have the least. To accommodate these high costs, federal poverty guidelines are 25 percent higher in Alaska than in the Lower 48. (Hawaii also has special poverty guidelines.) The guidelines are used to determine eligibility for a number of federal programs.
"In Alaska in 2010, a person was considered to be living in poverty if he or she earned up to $13,600 annually, or up to $27,940 for a family of four. For comparison, the average annual wage in the state was $47,700, as shown in the chart below. According to the 2010 American Community Survey, 9.9 percent of all individuals and 7.2 percent of families in Alaska were living at or below the poverty line."
