Estimations of population numbers in the Netherlands in prehistory are based in information from ethnography, burial places, traces from settlements and many assumptions. At the end of the Old Stone Age, presumably 1,000 people inhabited the area now called the Netherlands. By the end of the Middle Stone Age, this had grown to 2,000 people. In the New Stone Age, the population grew to about 10,000. The burial mounds of the Bronze Age are poor material to calculate with. By the end of prehistory, in the Iron Age, we must have had 30,000 people living in the Netherlands.
