Spatiotemporal topology of religious spread in a multi‐religious metropolis: A historical religious profile of Taipei City in Taiwan from 1660 to 2020.

Religious identities play an important role in shaping migrants' experiences. Understanding the spatiotemporal distribution of religions enhances our knowledge of both religious expansion and religious cultures. This paper aims to leverage spatiotemporal analysis to characterise the topology of the spread of multiple religions in the Taipei metropolitan area from 1660 to 2020, including Folk Taoism (853 temples/altars, 55.39%), Christianity (306 churches, 19.87%) and Buddhism (332 temples, 21.56%). Three major factors affecting religious distribution are considered: the year of establishment of religious units (churches, temples or altars), the reclamation year of religious locations, and the economic index of religious sites. The results show that Folk Taoism and Buddhism have a long history of development in early reclamation regions with a hopping expansion pattern. However, Christianity expanded later in the later reclaimed and early reclaimed areas. The Christian religious units have highly concentrated spatial patterns and are located in the higher‐income districts, centralised in the core regions of the Taipei metropolis. Modern forms of highly institutionalised religion, such as Buddhism and Christianity, are more prevalent in the relatively higher‐income, later‐cultivated areas, which provide richer social resources for development. Folk Taoism, as a traditional religion, is maintained and developed by local communities. This macroscopic analysis helps to (1) identify the exact chronology of different growth waves and explain them in a historical context, and (2) elucidate the spatial distribution differences between institutionalised religions and folk religion. Our research shows the evolution of religious landscapes from an undeveloped city to a developed city, offering valuable insights for geographical and religious studies, and enhancing understanding of diffused and institutionalised religious expansion.
