This article seeks to estimate various centrality indices based on spatial big data in terms of urban form, function, and location potential within a metropolitan area; it also comparatively analyzes the morphological differences in urban spatial structure between the centrality indices. As a result of estimating the centrality index for each dimension related to the urban spatial structure of the Seoul metropolitan region based on big data, the differentiated distribution patterns of urban centers were confirmed according to the characteristics of available big data by a quantitative and three-dimension morphological comparison methodology. The Mantel tests showed statistically significant mutual correlations between all centrality indices; however, the Passing–Bablok regressions revealed that the location potential centrality defined as Hansen-type accessibility was significantly different from the two centrality indices of the as urban form and function dimensions. The centrality of various dimensions in this paper includes not only the spatial characteristics of detailed spatial units but also the temporal characteristics theoretically. These results imply the need for comprehensive research to be carried out on urban spatial structure and centrality in accordance with the polycentric pattern of spatial structure in metropolitan areas. • Centralities in various dimensions were estimated based on spatial big data. • Centrality estimation methods are spatial convolution and accessibility calculation. • Distribution of city centers was different by urban form, function, and potential. • Pattern of location potential centrality was differentiated from other centralities.

This paper presents an ethnographic study of the Changsin-dong neighbourhood in Seoul, specifically focusing on urban development issues in the area, in which small-scale sewing workshops are agglomerated in the heart of the city. Under the names 'community alive' and 'existing urban manufacturing area,' Changsin-dong was designated as a leading area for urban regeneration in Seoul, and urban regeneration was implemented in 2014. Consequently, urban regeneration has now become an indispensable moniker for Changsin-dong, and conflicts related to various interests and political interference have arisen. Despite urban regeneration's emphasis on bottom-up approaches to overcome the limitations of developmentalism, hierarchical power relationships between governmental administrations and local cooperatives still persist over the entire course of the project. In this research, I critically examine the background surrounding how urban regeneration was fuelled and what consequences have been identified to date, and ultimately look at the subtle complexities and practical constraints of urban regeneration. Through macroscopic review of urban regeneration as well as microscopic anthropological observations, I seek to reveal the multi-layered socio-political contexts surrounding urban regeneration in Changsin-dong and unpack the nature of inevitable conflicts and contrasting interests among residents.

In this paper, I argue that intersectionality can benefit the study of migrant urban citizenship and that migrants' legal status affects their potential for urban citizenships. These arguments are based on life story interviews I conducted with Mongolian labour migrant women (both documented and undocumented) living and working in Seoul during the COVID-19 pandemic. Drawing from this data, I first discuss the mutual relationship between COVID-19 regulations and the specific urban spaces they affected, and second, how migrant women navigated this relationship. In practice, I categorise these pandemic-driven experiences into three specific types of spaces – spaces of escape , spaces of fear , and spaces of (potential) discrimination – which I analyse through the lenses of gender, class, and racialisation. In conclusion, I call for future research on migrant urban citizenship to critically consider the role of legal status in migrants' embodied processes of urban citizenship-making and investigate how underlying structural social and power relations shape these embodied processes. Reformulating the concept of urban citizenship in a way that explicitly informs policy making and fosters migrants' embodied experiences of urban citizenship is also needed. • Intersectionality can benefit the study of migrant urban citizenship. • Migrants' legal status affects their potential for urban citizenship. • COVID-19 regulations transformed urban spaces in Seoul into spaces of escape, fear, or discrimination. • Migrant urban citizenship needs to be reconceptualised into a policy-oriented approach.
