Hawaii Census Bureau Release: Hawaii State Subcounty Population Facts

The U.S. Census Bureau released its subcounty population estimates on May 25, 2017.  These annual statistics cover all local governmental units, including incorporated places such as cities and towns. Hawaii is the only state that has no incorporated places recognized by the U.S. Census Bureau.

Through an agreement with the Bureau, Urban Honolulu Census Designated Place (CDP) is the only subcounty area in Hawaii estimated by the Bureau on an annual basis. Urban Honolulu CDP encompasses an area bordered by Nimitz Highway, Aliamanu Drive, the Koolau Ridge, Waialae Nui Stream and Waialae Nui Canal.

From April 1, 2010 to July 1, 2016, Urban Honolulu CDP had a 4.2% growth in population and an increase from 337,719 to 351,792 people. This growth was about the same as the rest of Honolulu and the City and County of Honolulu, both with increases of 4.1%. It was, however, lower than the state (5.0%). It was also much lower than the growth for Maui County (6.8%), Hawaii County (7.2%) and Kauai County (7.4%).

Background information:  CDP stands for census-designated place. A CDP is an area identified by the U.S. Census Bureau for statistical purposes. CDPs are delineated for each decennial census as the statistical counterparts of incorporated places such as cities, towns, and villages. CDPs are communities that lack separate municipal government, but which otherwise physically resemble incorporated places. CDPs are delineated to provide data for settled concentrations of population that are identifiable by name but are not legally incorporated under the laws of the state in which they are located. The boundaries of a CDP have no legal status.

In 2010, the former Honolulu CDP was mostly divided into Urban Honolulu CDP and East Honolulu CDP. A small portion of the former Honolulu CDP became part of Hickam Housing CDP.
