In addition to the online military expenditure database covering the period 1988–2015, SIPRI is now making available a ‘beta’ version of an extended military expenditure dataset, with data going back in some cases to 1949, and to at least 1957 for a majority of countries that were independent at the time.
The new extended dataset, along with additional methodological information, is available on request. Please send an email giving your name and affiliation (if any) to email@example.com.
As a beta version, the new extended dataset is a work in progress. SIPRI welcomes feedback including on apparent errors or inconsistencies in the data, or on new sources of data that might help us fill in some of the gaps in the data.
