The State of Hawaii: 16,634.44 km² of land and 1,432,820 residents. Area is the Census Bureau’s land area (ALAND) for the state in the 2025 Gazetteer; it excludes 11,777 km² of inland and coastal water, so the land-plus-water total is 28,412 km². Population is the Census Bureau’s Vintage 2025 resident estimate for 1 July 2025, not a census count.
