Abstract In this essay I use Surabaya as a case study to argue that today's data-based urbanism excludes people from the city. Data-based urbanism differs from the revolutionary and counterrevolutionary urbanisms of the past in Surabaya that included people: the revolutionary form enabled the low-income majority of the kampung neighbourhoods to capture the ?city as a whole? through infrastructure, while the counterrevolutionary form enabled that majority to capture the city in parts through their kampungs. To make the aforementioned points I give the concept of heterotopia a Southern context that brings the low-income majority to the foreground of urban studies.
