a,b, Reported annual subnational birth (a) and death rates (b) for 2000–2019 are based on various global and national datasets with some of the intermediate results (Methods). c–f, For downscaling to 5 arcmin grid level, we used four annual gridded or subnational datasets of (c) human development index, (d) scaled population density, (e) share of reproductive women and (f) share of life lived in each grid cell, as detailed in the panels. g–i, The annual downscaled birth (g) and death (h) rates allowed us to estimate the natural population change for each year (i). j,k, When combining this with reported population change based on WorldPop55 (j), we were able to calculate annual net migration for 2000–2019 (k). See Methods for more details.
