IDA total economy graph showing purchasing power parity (PPP) growth from 2000 to today. Purchasing power parity adjusts the size of the economy to relevant price levels, i.e. measuring the price of specific goods in different countries and adjusting GDP accordingly.
The aggregate GDP per capita (PPP) of all IDA-eligible countries is markedly lower than the global average, emphasizing the need for sustained international development support. Common economic activities include subsistence agriculture, natural resource extraction, and informal markets.
