In the latter half of the 20th century, there were thus three major strands to the population – Mauritian and Seychelles contract workers (including management), and the Ilois. There is no agreement as to the numbers of Ilois living in the BIOT prior to 1971. However, the UK and Mauritius agreed in 1972 that there were 426 Ilois families numbering 1,151 individuals who left the Chagos for Mauritius voluntarily or involuntarily between 1965 and 1973. In 1977, the Mauritian government independently listed a total of 557 families totaling 2,323 people – 1,068 adults and 1,255 children – a number which included families that left voluntarily before the creation of the BIOT and never returned to the Chagos. The number reported by the Mauritian government in 1978 to have received compensation was 2,365, consisting of 1,081 adults and 1,284 minor children. The Mauritian Government's Ilois Trust Fund Board certified 1,579 individuals as Ilois in 1982.
