The primary reason for Hilo International Airport's relatively stagnant passenger count is the lack of tourism within the airport's service area, which includes the districts of Hilo and Puna, as well as portions of the districts of Hāmākua and Kaū, relative to the Kona district and Kohala district and the islands of Kauai and Maui. In 2008, visitor hotel rooms and condominiums on Hawaii island totaled 11,240 units. Of these, 9,576 (85.2%) were in the districts of Kona and Kohala. A mere 1,635 (14.5%) were within the districts of Hāmākua, Hilo, and Puna. In 2008, the respective numbers of visitor accommodations on Maui and Kauai were 19,055 and 9,203. In fact, whereas the number of visitor accommodations elsewhere in the state climbed steadily since the 1970s, in east Hawaii island several hotels have been shuttered or converted into apartments or condominiums.
