The world’s Middle Income Countries (MICs) are a diverse group by size, population, and income level. For the current 2024 fiscal year, low-income economies are defined as those with a GNI per capita, calculated using the World Bank Atlas method, of $1,135 or less in 2022. Lower middle-income economies are those with a GNI per capita between $1,136 and $4,465; upper middle-income economies are those with a GNI per capita between $4,466 and $13,845; high-income economies are those with a GNI per capita of $13,846 or more, according to the World Bank Country and Lending Groups.
Middle income countries are home to 75% of the world’s population and 62% of the world’s poor. At the same time, MICs represent about one third of global GDP and are major engines of global growth.
The World Bank Group continues to evolve its partnership with MICs, working with them simultaneously as clients, shareholders, and global actors. The World Bank provides increasingly tailored services—financial products (loans, guarantees, risk management products) and knowledge and advisory services (including on a reimbursable basis)—to support MICs in their global roles, to address their second-generation reform challenges, and to facilitate knowledge exchange and South-South cooperation.
