Kapolei is becoming the second urban center for Oahu (after Honolulu), Hawaii's most densely populated island. Much of Oahu's future population growth is slated forundefinedthe ʻEwa Plain and southern slopes of the island's central valley, between Waipahu on Pearl Harbor and Wahiawa near the island's center.
Initial residential construction began in the late 1980s, with commercial developments shortly after. Despite ongoing efforts at self-sufficiency, it remains largely a bedroom community.
Kapolei is home to a public library, post office and schools, including Kapolei High School. A private school (pre-K through 12) opened in 2004. Construction of Kapolei Courthouse began in July 2007.
The U.S. postal code for Kapolei is 96707. In 2002, Pacific Business News reported that 96707 had the second highest median income on the island of Oahu, at $62,303. Sterlings's Best Places reports Kapolei median income of $70,129 compared to the national average of $42,350. Nearly one household in five has income exceeding $100,000.
