The 2010 American Samoa Population and Housing Census was conducted as part of the United States Decennial Census, in cooperation with the local government. The 2010 Census of the Pacific Island Areas operated on a different timeline than that of the states. Field work was undertaken by local census offices, and overseen by the U.S. Census Bureau. During the data collection period, residents of the island areas either completed self-administered questionnaires, or were interviewed by enumerators. A feature specific to the census of the Pacific Island Areas was the completion of long-form questionnaires only, whereas the stateside census used only the short form. Edits made to the form for the island areas included languages spoken in a household, wording of questions on U.S. Citizenship and birth place, and the receipt of Supplemental Security Income added to the question on Public Social Assistance or Welfare. The total enumerated population of American Samoa in 2010 was 55,519.
