The SIPRI (Stockholm International Peace Research Institute) Military Expenditure Database contains consistent time series on the military spending of countries for the period 1949–2017.
The database is updated annually, which may include updates to data for any of the years included in the database.
Military expenditure in local currency at current prices is presented recently, according to both the financial year of each country and according to the calendar year, calculated on the assumption that, where financial years do not correspond to calendar years, spending is distributed evenly through the year.
Additionally, figures in constant (2016) and current US$, as a share of GDP and per capita are presented according to the calendar year. Figures as a share of government expenditure are presented according to the financial year.
