World Bank - International Development Association (IDA).
The IDA aims to reduce poverty in the world's poorest countries by providing loans and grants for programmes that boost economic growth, reduce inequalities, and improve living conditions.
Eligibility for IDA support depends primarily on a country’s relative poverty, defined as gross national income (GNI) per capita below an established threshold, and updated annually.
IDA also supports some countries, including several small island economies, that are above this GNI level, but lack the creditworthiness needed to borrow from the International Bank for Reconstruction and Development (IBRD).
Some countries are IDA-eligible based on per capita income levels and are also creditworthy for some IBRD borrowing. They are referred to as “blend” countries.
Between 70 and 80 borrowing countries were eligible to receive IDA support in 2020.
