Each country is identified by its ISO-3 country code (https://www.worlddata.info/countrycodes.php). The average spatial resolution (ASR) was calculated as the square root of each country’s surface area divided by the number of administrative units, and represents the effective resolution of the latter (i.e., the cell size of administrative units if all units were square of equal size)²². Countries with fewer than 25 administrative units were modelled with additional countries, selected based on similar characteristics; ‘Grouped Islands’ refers to a set of countries that were modelled simultaneously, including: BHS, TCA, CYM, VGB, KNA, ATG, MSR, DMA, LCA, BRB, GRD, TTO, BMU, VCT, AIA, MSR, VGB. Superscripts ‘C’ or ‘P’ in the 8^th column, indicate whether population statistics were obtained from either official census or census-based projections, respectively.
