 The social structure among Fijian Hindus has lacked any caste structure.Scholars suggest that this lack of formation or observance of caste system among Fijian Hindus may have been because of the nature of work in Fijian plantations where everyone's profession revolved around farming, because Fijian Hindus lived together from the time they arrived in coolie ships, and because of demographic constraints faced by them.Extensive exogamy has been observed among Hindus of Fiji since the earliest days of plantation settlements, just like in other major indentured Hindu labor settlements in Mauritius, Natal (South Africa) and the Caribbean.
