How might concepts of ‘value’ and ‘population’ illuminate the present and future of urban density? The Covid-19 pandemic prompted a public debate on density in the city. While some initially blamed density for the spread of the virus, others rightly cautioned against those claims. As the pandemic progressed, an imaginary of density-as-pathology gave way to a more nuanced geographical understanding of the urban dimensions of the crisis, focussed on connections, spatial conditions, domestic ‘overcrowding,’ and poverty. Throughout, an interrogation and reflection on urban density and its future unfolded, throwing into question the historical relationship between ‘value’ and ‘population’ in understandings of density. I argue for a new politics of value based on shifts in three inter-connected domains - governance, form, and knowledge - and identify implications for research on density in urban studies
