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.

Hawaii is the only state that has no incorporated places recognized by the U.S. Census Bureau. The City and County of Honolulu is reported as Honolulu CDP and the balance of Honolulu.

Honolulu CDP consists of Honolulu District, comprising the area between Red Hill and Makapuu Point, south and southwest of the crest of the Koolau Mountains and the Northwestern Hawaiian Islands. Honolulu and Arlington are the only CDPs for which
postcensal population estimates are calculated by the U.S. Census Bureau.

From April 1, 2000 to July 1, 2009, Honolulu CDP had only a 0.8% growth in population, from 371,657 in April 1, 2000 to 374,701 in July 1, 2009. This is the smallest growth compared with other counties in Hawaii, except Kalawao County where population
actually decreased by 43.5%.

The rest of Honolulu gained 5.6% in population during thesame time period.

The largest growth in population occurred in Hawaii County at 19.6%, followed by Maui County at 13.3%. Kauai County had a population growth of 10.4% between the two time periods. Statewide population growth was 6.9%.

Honolulu CDP accounted for 41.3% of Oahu’s population in 2009, while 58.7% of Oahu’s population lived in the rest of Oahu. On April 1, 2000, Honolulu CDP shared 42.4% of Oahu’s population. Over the years, population in Honolulu CDP grew slower
than other parts of Honolulu due to residential constructions outside of the Honolulu CDP.

Census Bureau used building permit information as the base for the population estimate. New York City as the most populous city in the U.S. with 8.4 million people, followed by Los Angeles with 3.8 million people. Chicago is ranked the third largest city with a
population of 2.9 million. Houston and Phoenix were the next two in population size with 2.3 million and 1.6 million people, respectively.
