The Alaska PFD has decreased poverty within Alaska by 20% [0]. An extra $2-3k can have a massive impact in a state where a significant minority lives in rural/isolated regions and/or reservations. That additional $2-3k added with SNAP benefits has helped thousands of Alaskans a year keep food on their table.
In addition, Native Corporations (ANSCA) help alleviate poverty further by spreading commodities income to all members of that native tribe (eg. all Inuit from Utquiatvik will get a check from the Arctic Slope Regional Corporation thanks to revenue generated by Shell and Cheveron).
