Abstract
Worldwide, about one in eight people live in slums. Empirical studies based on satellite data have identified that the size distributions of this type of settlement are similar in different cities of the Global South. Based on these results, we developed a model describing the formation of slums with a Turing mechanism, in which patterns are created by diffusion-driven instability and the inherent characteristic length of the system is independent of boundary conditions. We examine the model in this paper by critically reflecting its assumptions, comparing them with recent empirical observations and discussing possible adjustments and future extensions based on new methods of identifying pattern formation mechanisms.

Comment:
We updated the discussion, the name of the article, since clustering isn't the focus of the paper anymore, added a new paragraph named "General reflections" and updated the Figures. While the first version of the article was based mainly on simulation results of a study by Hartig, the major changes to the second version and also to this current third version were made by John Friesen. Since the most recent version and the now added section "General Reflections" were largely written by John Friesen, the authors agreed unanimously to change the order of authorship.
