When Emusoi started in 1999, the centre welcomed its first 6 students all belonging to the Maasai tribe. But before the end of the year, the population grew to 20 girls. At present, the centre has grown to having 350 girls every school year. With that growth come the welcoming of other pastoralist and hunter-gatherer tribes in Tanzania namely the Hadzabe, the Barbaig, the Datoga, and the Taturu.
