Figure A.1: Population Diversity and Proximate Determinants of the Frequency of Civil Conflict Onset across Countries.

Notes: This figure depicts the global cross-country relationship between contemporary population diversity and each of three potentially conflict-augmenting proximate channels, including (i) the degree of cultural fragmentation, as reflected by the number of ethnic groups in the national population (Panel (a)); (ii) the prevalence of generalized interpersonal trust at the country level (Panel (b)); and (iii) the extent of heterogeneity in preferences for redistribution and public-goods provision, as reflected by the intra-country dispersion in individual political attitudes on a politically “left”–“right” categorical scale (Panel (c)), conditional on the baseline geographical correlates of conflict, as considered by the analysis in Table VII. Each of Panels (a), (b), and (c) presents an added-variable plot with a partial regression line, corresponding to the estimated coefficient associated with population diversity in Columns 1, 4, and 7, respectively, of Table VII.
