The M3-Dataset represents the most comprehensive global dataset for the multidimensional exploration of militarization. It draws on a conceptualization of militarization as a multidimensional phenomenon, differentiating between the dimension of material, political and societal militarization. We thereby understand militarization as a change in state-soldier-society relations: The more missions and resources are laid into the hands of the military, the greater the degree of militarization. The M3-Dataset provides 30 variables and overall, 140.000 observations on three dimensions of militarization since 1990. It consists of qualitative expert-coded and quantitative statistical indicators. Please find more information about M3, the dataset and replication materials here.
