The articles in this special section argue that, by looking at quantification as a technical and political technique of power, we can effectively engage with newly established types of transnational power and better under-stand how numbers can enable reconfigurations and hence reorderings of power relations. The section looks at how numbers, in the form of risk assessments, measuring for results, and governance indicators, have a crucial impact in current transnational politics, which in turn influences resource allocation and recognition, discourses on undesirable individuals, possibilities for political leverage, and potential ownership.
