Honolulu

Honolulu County is a consolidated city–county in the U.S. state of Hawaii. The city–county includes both the city of Honolulu and the rest of the island of Oʻahu, as well as several minor outlying islands, including all of the Northwestern Hawaiian Islands except Midway Atoll.The consolidated city-county was established in the city charter adopted in 1907 and accepted by the Legislature of the Territory of Hawaiʻi. As a municipal corporation and jurisdiction it manages aspects of government traditionally exercised by both municipalities and counties in the rest of the United States.

As of the 2020 United States Census, the population was 1,016,508. Because of Hawaii's municipal structure, the United States Census Bureau divides Honolulu County into several census-designated places for statistical purposes.
