This map layer presents global arms imports for 2017 based on the trend indicator value (TIV) developed by SIPRI, measured in US dollars and classified in five categories. Even though it is measured in US dollars, the indicator does not show the financial volume of arms transfers but gives an indication of the scope of traded weapons in comparison to other countries.
Example of how to read the map:
In 2017, Belgium imported arms and related materials worth US $12 Mio. as trend indicator value (TIV).

In its annual yearbook, SIPRI publishes current global imports and exports of arms and related materiel of countries. For this, it uses a system that it created which is based on indicators of different values. Each weapons system is allocated a value, a so-called TIV (trend indicator value). With the help of the TIV, SIPRI calculates all weapons transfers to, from and between countries and non-state actors and obtains an indicator for the scope of the transfers. SIPRI collects the data from primary sources, such as data from national governments or the United Nations, evaluations of these sources as well as further secondary sources, such as journals and newspapers.
