Eskimo is a general term for the population from Alaska to Grenland and Asia. Eskimos in Canada and Greenland use the name Inuit (inuk = human beeing). Sea mammals, fish and caribou are important for food and economy. Igloos are used as a winter residence, in the summer tents of caribou skins provide shelter. The dogsleds are used for the nomadic huntig life. Traditional weapons were crafted from ivory and bones. Eskimo population in the United States is about 60,000 and 33,000 in Canada. In these states Eskimos live in settled communities. Instead of the dogsled they use the snowmobile and instead of traditional weapons firearms.
