The Statistics of Public Expenditure for Economic Development (SPEED) database contains information on agricultural expenditures in 112 developing countries and 34 developed countries.

Global per capita agricultural spending rose at an annual rate of 0.33 percent from 1980 to 2012. A decline between 1980 and 2000 was off-set by growth within the last 12 years.

On average, agriculture accounts for about 2-3 percent of total government expenditure. For developed countries, despite their large volume of investments, agriculture represents only a marginal portion of the economy. Per capita expenditure declined continuously in 1980–2012, and averaged $102 per person in the 2000s. The share of agriculture in total government budget also dropped to about 1 percent in the past decade, but the ratio of agricultural expenditure to agricultural GDP remained high at above 20 percent.

In developing countries, although agriculture accounts for a larger share of total expenditures, per capita spending was considerably lower and was only a fraction of the level in developed countries.

The SPEED data are compiled from: the United Nations Statistical database for complete time-series of the GDP deflator, the World Bank for exchange rate and purchasing power parity (PPP) conversion factors, as well as orher sources (International Monetary Fund, national governments).
