This is the fourth annual Cluster Munition Monitor report. It is the sister publication to the Landmine Monitor report, which has been issued annually since 1999.

Cluster Munition Monitor reviews every country in the world with respect to cluster munition ban policy as well as cluster munition use, production, trade, and stockpiling. It also contains information on cluster munition contamination and clearance activities, as well as casualties and victim assistance. Its principal frame of reference is the Convention on Cluster Munitions, although other relevant international law is reviewed, including the Convention on Conventional Weapons.

The report focuses on calendar year 2012, with information included up to July 2013 where possible.
