Estimates of Tasmania's Aboriginal population in 1803, the year of the first British arrivals, range from 3,000 to 7,000. Lyndall Ryan's analysis of population studies led her to conclude that there were about 7,000 spread throughout the island's nine nations;[68] However, Nicholas Clements, citing research by N.J.B Plomley and Rhys Jones, settled on a figure of 3,000 to 4,000; this number being a more reasonable number when the circumstances of Indigenous life are factored in.[69]
