The SIPRI database provides data on military expenditure for more than 160 countries. The SIPRI provides data for the period of 1949-2024 (or most recent year) and it is updated annually.
Military expenditure in local currency at current prices is presented according to both the financial year of each country and according to calendar year, calculated on the assumption that, where financial years do not correspond to calendar years, spending is distributed evenly through the year. Figures in constant (2023) and current US dollars, as a share of gross domestic product (GDP) and per capita are presented according to calendar year. Figures given as a share of government expenditure are presented according to financial year. The online database is available at https://www.sipri.org/databases/milex.
The sources for military expenditure data are, in order of priority: (a) primary sources, that is, official data provided by national governments, either in their official publications or in response to questionnaires; (b) secondary sources which quote primary data; and (c) other secondary sources. The second category includes international statistics, such as those of NATO and the International Monetary Fund (IMF).
SIPRI military expenditure data is based on open sources only. The database is revised when new and better sources are available. Therefore, there is sometimes considerable variation between data sets for individual countries in different yearbooks. The availability of data varies considerably by country, but for a majority of countries that were independent at the time, data is available from at least the late 1950s. Estimates for regional military expenditure have been extended backwards depending on availability of data for countries in the region, but no estimates for total world military expenditure are available before 1988 due to the lack of data for the Soviet Union.
