SIPRI Military Expenditure Database
- in local currency, at current prices. 1988-2013
- in US dollars, at constant (2011) prices and exchange rates, 1988-2013
- in current US dollars, converted at the exchange rate for each year (not NATO before 1988)
- as a share (%) of gross domestic product (GDP), 1988-2013
- per capita (not NATO before 1988)
- as a share of government expenditure (not NATO before 1988)
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 (2011) and current US$, as a share of GDP and per capita are presented according to calendar year. Figures as a share of government expenditure are presented according to financial year.
SIPRI military expenditure data is based on open sources only, including a SIPRI questionnaire which is sent out annually to all countries included in the database. For some NATO member states, and for most data on then-NATO members before 1988, NATO’s annual press releases on Financial and Economic Data on NATO Defence is a key source. The collected data is processed to achieve consistent time series which are, as far as possible, in accordance with the SIPRI definition of military expenditure, detailed in the sources and methods.
SIPRI data may be freely downloaded, cited, and used for statistical or other analytical purposes. Any reproduction—in any medium, electronic or printed—of the data requires authorization, except as noted below. Permission may be granted provided that:
- A request for permission is submitted to SIPRI. A request must include your full name, where you are from, your affiliation, and for what purposes you require the data.
- Attribution to SIPRI in a source credit-line is given, including the phrase "Information from the Stockholm International Peace Research Institute (SIPRI), URL ADDRESS". This applies to both citations and reproduction.
When text or data is to be used for commercial purposes, and once permission has been obtained, the parties will negotiate a reasonable royalty for such commercial use.
You do NOT need permission to use or cite SIPRI data for the following purposes, so long as SIPRI is clearly identified as the source of the data:
- In a university/school/college paper, essay or dissertation
- In an academic journal article, monograph or book chapter
- In a newspaper or magazine article
- In a blog post
This includes producing graphs and charts based on the data.
For such purposes, permission is only needed if you want to directly reproduce more than 10% of the database. That's about 500 separate pieces of data. In other words, you almost certainly don't need permission. (It's fine to use as much of the data as you like for e.g. econometric analysis. It's only direct republishing of the data itself that requires permission for large volumes).
