A The relative variability (CV) of the national footprints compared to their absolute size assuming proportional import shares. Boxplots show the distributions of the CVs across the 49 regions to facilitate comparison between the different types of footprints. Country codes according to ISO 3166-1 alpha-3 except RoW regions (see Additional file 5). B The sample distributions of the national footprints exemplary for some selected interesting regions. The footprints where normalised by dividing each sample by the mean of all 4897 samples. The violin plots show the probability density and the range of all samples. The boxplots show the inter-quartile range (IQR) where 50% of all samples are situated (boxes), the sample’s median (horizontal line) and the range from the 2.5th to the 97.5th percentile (whiskers). The red points show the footprints size assuming proportional import shares, also normalised by the mean of all samples
