Hawaii Population History
Hawaii was an independent nation prior to being annexed by the United States in 1898; it was made a territory in 1900. On August 21, 1959, Hawaii was admitted as a State and assumed its present boundaries, omitting certain small islands formerly included in the territory.
Census coverage has included the whole of Hawaii since 1900. The Hawaiian government conducted at least 9 censuses between 1850 and 1898; see Robert C Schmitt, Historical Statistics of Hawaii (Honolulu: University Press of Hawaii, 1977).
