Tuna canning is the main economic activity in town. Exports are almost exclusively tuna canneries such as Chicken of the Sea and StarKist, which are both located in Pago Pago. These also occupy 14 percent of American Samoa's total workforce as of 2014. The most industrialized area in the territory can be found between Pago Pago Harbor and the Tafuna-Leone Plain, which also are the two most densely populated places in the islands.
