Jakarta has officially become the world’s largest city, overtaking Tokyo according to a new United Nations population report released this week. The milestone reflects decades of rapid urbanization, driven by internal migration, expanding metropolitan borders, and rising commercial activity.
The UN report highlights that while Jakarta’s population boom underscores its economic importance, it also intensifies challenges related to congestion, flooding, and infrastructure strain. Urban planners warn that the city’s already stretched transport network and housing systems may struggle to keep pace.
Authorities have reaffirmed ongoing plans to shift the national capital to East Kalimantan, but they say Jakarta will remain the nation’s business hub regardless of administrative relocation.
Social groups are urging the government to invest more aggressively in climate resilience, noting that Jakarta remains one of the world’s most flood-prone coastal cities.
The UN report concludes that Jakarta’s demographic shift signals a broader pattern of megacity expansion across Southeast Asia, where rising populations continue to transform regional economic landscapes.
