The City and County of Honolulu covers the entire island of Oahu, nearly 600 square miles, and its Citizen-Centric Report puts the county's 2024 resident population at an estimated 998,747, about 69.1% of the state's total. The same report describes tourism as the city's primary industry, followed by federal defense expenditures, and notes that military expenditures account for nearly 66,000 Honolulu jobs while defense contract and personnel spending totaled $9.1 billion. Visitor volume keeps the retail and service base busy: the state counted 540,147 visitors to Oahu in December 2024, and 5,814,176 across calendar 2024. For a small business, that mix means demand swings with the season and the flight schedule, and the establishment counts below reflect a metro that is really one island's economy.
