• The passthrough of national growth to household incomes varies across country contexts, including geography, income level and distribution, and income measurement instrument.

• Lower-income countries exhibit lower growth passthrough rates, but the passthrough rates increase with the level of development.

• The Arab region stands out globally, exhibiting an overall low passthrough rate but also a great divergence of passthrough rates across its subregions.

• Developing countries in the Arab region and elsewhere should be concerned with macroeconomic and distribution policies that enhance aggregate income growth – especially in poorer countries with lower income and expenditure per capita and with greater scope for enhancing the passthrough of growth to households.
