The Solomon Islands were granted independence in 1978. The first prime minister was Peter Kenilorea from 'Are'are (Malaita). The provinces were re-organized in 1981, and Malaita became the main island of Malaita Province. Malaita remains the most populous island in the country, and continues to be a source for migrants, a role it played since the days of the labour trade. There are villages of Malaitans in many provinces, including eight "squatter" settlements that make up about 15 percent of the population of Honiara, on Guadalcanal.
