Over the past twenty years or so, Mexico City, like most Latin American metropolises, has undergone a dual process of increasing urban sprawl on the one hand, and densification of the city center and inner ring older suburbs (innerburbs) on the other, and has entered a “settlement stage” in which intra-urban residential trajectories are more numerous and more complex. In so doing, as multiple authors have shown, these are signs of urban change and ways of inhabiting the city. This Blog seeks to explore these complex mobilities and experiences. Analysis of intra-urban mobility, as worked on by members of the Latin American Housing Network comparative studies (Di Virgilio, 2023; Ward, 2023) and others, helps to refine our understanding of the churn (“change” and “turn”) of consolidated working-class peripheries. Such churn raises issues of residential stability, densification, the rewriting of socio-spatial division, the ageing of an already fragile housing stock, property valuation, and potential returns to irregularity within a context of renewed precariousness of access to housing. It also reveals mechanisms for anchoring populations and maturing residential contexts which I will discuss below.
