Using available growth forecasts, we estimate that compared to the business-as-usual scenario (scenario i), the average income per capita annual growth rates for the 108 countries included in the SIGI ranking would increase by 0.03 percentage point in the upgrade in the SIGI classification scenario (scenario ii), by 0.2 percentage point in the best-in-region scenario (scenario iii) and by 0.6 percentage point in the gender parity scenario (scenario iv). Annex I presents country examples using regional lowest performers in the SIGI, which are Albania, Bangladesh, Nicaragua, Sudan, Turkey and Yemen. The simulation findings show sizeable income gains for each scenario.
