The population density in Alaska is 1.3 people per square mile (56th out of 56). caribou eat the leaves of willows, sedges, flowering tundra plants, and mushrooms. Although overhunting caused some herds to remain low in the past, today, varying weather patterns (climate), population density, predation by wolves and grizzly bears, and disease outbreaks determine whether most herds increase or decrease. Caribou movements are probably triggered by changing weather conditions, such as the onset of cold weather or snowstorms.

Ranked at number seven in the nation, this state experienced growth of 54.2% of its Asian population between the 2000 and 2010 censuses.
