Median of the ratio of food producers over hunter-gatherers for Ne (a), NPP (b) and Ne/NPP (c) in the three regions considered: sub-Saharan Africa, south-eastern Asia and Oceania, and Siberia. The plots show the temporal range between 4,000 and 20,000 years ago for dataset 1 and between 7,000 and 20,000 years ago for dataset 2. The error bars represent the 95% distribution of the jackknife leave-one-out validation.
