Extended Data Fig. 4: Single variable comparison between Global North and South.

Violin plots showing median, quartiles, and the distributions of the families of criteria described by the four latent factors resulting from the principal factor analysis. Here, factor strength is the overall impact of the measured factor in explaining the observed data (factor score for each policy). Note: The correlation among criteria, the factor loadings and their variance, the factor scores and their graphical representation through kernel density and boxplots are all based on the weighted sample. N for Global North = 165 and for Global South = 367.
