According to data released by the 2010 census, Hawaii's population grew about 12.3% to 1,360,301 people in the last decade. The largest jumps were in Maui (20.9%) and Hawaii (24.5%) counties.
In Honolulu County, on Oahu, the Ewa Gentry area saw the largest percentage growth, 359.4%, out of all areas in the state. In 2000 there were 4,939 residents, but by 2010, there were 22,690. Pearl City had 54% growth, to 47,698 people.
Urban Honolulu is the most populous area, with 337,256 people. Oahu tallied 953,207 residents.
It is hard to predict whether any Oahu districts will require changes in voting representation. Despite the large growth on Hawaii (Big Island) and Maui, they are unlikely to see more seats in the state Legislature.
Asians make up the largest ethnic population throughout the state, 38.6% with about 525,100 people. There are roughly 135,400 native Hawaiians in the state, and 336,600 whites. As of 2010, there are 2.6% fewer blacks in Hawaii, down to approximately 21,400.
Hawaii has always been an ethnic melting pot, and reinforces our Aloha spirit. There are very few who don't feel welcome as soon as they arrive. If you are considering relocation, ask for my free relocation package, on my web site, which has just been updated with news on the "greening of Oahu."
