Mapping Arms Data

The Igarapé Institute launched the updated Mapping Arms Data (MAD) visualization tool in 2013. Check out the explanation of MAD

The MAD project is based on the original small arms and ammunition visualization produced by Google, Igarapé Institute and the Peace Research Institute Oslo as part of the Google Ideas INFO (Illicit Networks Forces in Opposition) Summit in 2012.

Today, MAD features over 35.000 records of the exports and imports of small arms, light weapons and ammunition from more than 262 states and territories between 1992 and 2011. The updated tool incorporates additional data and new features and was launched in 2013. To read more about MAD, consult our FAQs.


MAD has been viewed by over 2 million people since mid-2012 and been featured in hundreds of international, regional and national media outlets. Recent examples include: Favorite Website Award (2012), honorary nomination for a Webby (2013) and  recent features in Wired magazine (2013)  and BBC (2013).
