The US Central Intelligence Agency (CIA) reports that in 2001 Burundi's gross domestic product (GDP) was estimated at $3.7 billion. The per capita GDP was estimated at $600. The annual growth rate of GDP was estimated at 1.4%. The average inflation rate in 2001 was 14%. The CIA defines GDP as the value of all final goods and services produced within a nation in a given year and computed on the basis of purchasing power parity (PPP) rather than value as measured on the basis of the rate of exchange. It was estimated that agriculture accounted for 50% of GDP, industry 18%, and services 32%. Foreign aid receipts amounted to about $19 per capita and accounted for approximately 19% of the gross national income (GNI).
The World Bank reports that in 2001 per capita household consumption (in constant 1995 US dollars) was $122. Household consumption includes expenditures of individuals, households, and nongovernmental organizations on goods and services, excluding purchases of dwellings. It was estimated that for the same period private consumption grew at an annual rate of 13%. The richest 10% of the population accounted for approximately 32.9% of household consumption and the poorest 10% approximately 1.8%. It was estimated that in 2001 about 70% of the population had incomes below the poverty line.
