In this chapter, I present a conceptual proposal for the systematic theorization of the concept of demographization, and also propose to reconstruct an underlying Malthusian matrix. Unraveling the complex processes of how demographic rationalities are shaping government agendas requires the integration of various important dimensions of reproductive racism and of population as an intrinsically hierarchical concept. In general, the concept of demographization gives us a way of reflecting the reifying effects of population statistics as an apology for the status quo, providing the basis for blaming those groups affected by social crises for being the quantitative manifestation or even cause of those crises. The concept thus provides a systemic approach to how apparently neutral and quantitative abstract demographic crisis narratives are inseparably entangled with hierarchical racist and classist strategies of de/valuation. Furthermore, it makes it possible to approach the intrinsic methodological nationalism of policies based on demographic knowledge production. And, when taking into account how gendered policies directed to individual reproductive bodies are entangled with racist and class-selective policies addressing population(s), it offers important insights into how to develop a state-theoretical and structural approach to the intersectionality of reproductive policies. For this purpose, the Foucauldian concept of biopolitical poles helps us to understand reproductive relations as the hinge between body and population policies. However, in the text I will also explore the limits of Foucault's approach to population by favoring an intersectional approach, emphasizing racist and classist selectivities and the genealogy of the Malthusian matrix. The chapter is based on my research on the demographization of German family and migration politics in the 2000s and 2010s, and takes these developments as its main exemplifying reference. It therefore focuses on the demographization of established government policies and only touches on the current dangerous upswing of right-wing racist and nationalist population agendas in passing. Moreover, the chapter therefore concentrates on demographization within a selectively pronatalist agenda. However, in the last section the concept is applied to transnational antinatalist policies toward the Global South.
