I would wager that the majority of those humans attacked, wrong word, are visitors or surfers. Rarely, in my life here, over fifty years, have true locals been in the wrong place at the right time. The exception to this is driving, usually at dark and riding waves early or late in the day especially in fall. The sharks usually are not "attacking" so much as defending a territory or their young. In the southern Pacific, the islanders rarely have negative encounters with sharks. I know this because I gave spent years both there and in Hawaii surfing and diving. Learn their ways, ask the Kapuna, be aware of the season and the condition of the ocean. The hotels must spend more time educating their guests.
