30096 Marubo 1000-9999 The 1995 Ethnologue lists an estimate of 594 speakers of the Marúbo. According to demographics illustrated on the Socioambiental web site ... in 2000, there were 1,043 Marúbo, living in four locations. This figure is more likely the accurate figure, since it is based on ongoing demographic research. This research began in 1975 and has continued at least through the year 2000. Due to population growth, the actual population total is likely even higher. (pp.9-10)
