Fig. 2. Model predictions for areas where languages are likely to become endangered (EGIDS ≥ 6b) in the next 40 years, given the best model.

Fig. 2

a,b, The red shading represents the differences between the predicted values at present and the predicted values in 40 years, for the absolute number (a) and proportion of languages (b) per hex grid, based on generational shift and demographic transition in L1 speakers. c, Proportion of languages predicted to become Sleeping (EGIDS ≥ 9) in the next 40 years. See Supplementary Table 1 for information on endangerment scales. Language distribution data from WLMS 16 (worldgeodatasets.com).
