Heterogeneity in convergence. The ratio between the poorest and least poor in the earliest (Initial) and most recent (Final) year of measurement within each survey shows that the mortality ratio has been diverging in 21 of the 85 surveys. Three-letter country codes identify the countries with divergence of mortality across the wealth gradient, measured as increasing mortality rate ratios over time (ARM, Armenia; AZE, Azerbaijan; BDI, Burundi; BFA, Burkina Faso; COD, Democratic Republic of the Congo; COG, Congo; ETH, Ethiopia; GUY, Guyana; HND, Honduras; HTI, Haiti; KHM, Cambodia; LSO, Lesotho; MLI, Mali; MWI, Malawi; NGA, Nigeria; PHL, Philippines; RWA, Rwanda; TLS, Timor; UKR, Ukraine).
