Hawaii's economy faces unique challenges due to its isolation and reliance on imports, leading to a high cost of living. Transportation costs are factored into nearly all consumer goods, and housing remains disproportionately expensive compared to mainland states. Building materials, mostly imported, are costly, and residential land has historically been limited and highly priced, though recent legislation has addressed some of these issues for single-family homeowners.
Agriculture remains a vital part of Hawaii's economy, with a diverse range of food and ornamental plants grown commercially or for home consumption. While sugarcane and pineapple production have declined due to lower labor costs in other regions, crops like coffee, macadamia nuts, and ginger root have seen steady growth. Ranching, particularly on the Big Island, is another important sector, with a long-standing tradition of paniolos, or Hawaiian cowboys, managing herds in much the same way as they have for decades.
Hawaii has limited natural resources, relying primarily on its climate, water supply, soil, and surrounding ocean. The state still depends heavily on imported oil for energy, though it has made efforts to increase the use of renewable sources like geothermal and wind power. Manufacturing in Hawaii is diversified, with heavy industries such as oil refineries and aluminum extrusion plants primarily located on Oahu. The state also processes and exports a variety of locally grown foodstuffs, including tropical fruit juices, coffee, and macadamia nuts.
Tourism is Hawaii's largest industry, with visitors primarily coming from the U.S. mainland, Canada, Australia, and Asia. The sector has expanded rapidly since World War II, supported by improvements in transportation and investments from mainland and foreign companies. About one in four Hawaiian workers belong to a union, with the International Longshore and Warehouse Union (ILWU) having played a significant role in the state's history. However, the ILWU's influence has waned with the decline of sugar and pineapple production.
