The economy is based on services and manufacturing. The government is the main employer. A large part of the national income comes in the form of grants from the U.S. federal government. Tuna canning (by American-owned canneries) and tourism are major industries. Agriculture is organized on a semi commercial basis for the production of taro, bananas, tropical fruits, and vegetables. Traditional family gardens produce coconuts, breadfruit, and yams. Production nearly meets domestic needs, and the U.S. government has implemented programs to increase production to self-sufficiency levels. The United States and Singapore are the main sources of imports (which include fish destined for the canneries, consumer goods, food, and mineral fuels), although Fiji and New Zealand are also notable exporters of goods to American Samoa. The United States is the primary destination for exports, which consist mostly of canned tuna, along with a small amount of pet food.
