AbstractThe expansion of social citizenship in the 20th century mitigated the brute effects of economic inequality in people's lives. The new rights also created new social divisions, however, separating citizens according to their ability to do well through them. In the 21st century the conceptual matrix of citizenship has developed further, powered by new technologies that have promised new freedoms and opportunities in every aspect of people's lives. As the scope of economic and social incorporation has broadened, the possibilities for classifying, sorting, slotting, and scaling people have also grown and diversified. Echoing the earlier rise of the meritocracy, this new matrix produces its own winners and losers, partly recycling old inequalities, and partly creating new ones. Demands for self‐care and individual fitness pile up, eroding the universal and solidaristic basis upon which the expansion of citizenship historically thrived. In its place stands what I call “ordinal citizenship,” a form of social inclusion that thrives on social measurement, differentiation, and hierarchy.
