Background: Urbanization can improve productivity by bringing workers, firms and services closer together, but those gains are not automatic. When housing, mobility and public services lag behind population growth, the same density that supports opportunity can deepen exclusion. Aims: This article examines the mechanisms that connect the topic to organizational or policy performance and identifies the conditions that make those mechanisms stronger or weaker. Research Method: A structured narrative review integrates peer-reviewed research with authoritative policy, statistical, and professional sources, including BPS (2026); UNDP (2025). Sources are coded by outcome, mechanism, boundary condition, and practical implication. Results and Conclusion: The synthesis indicates that outcomes are heterogeneous. Social welfare policy cannot compensate indefinitely for weak urban systems. Cash support matters, yet households remain vulnerable when affordable housing, transport, health, education and climate-resilient infrastructure are unavailable. Six recurring themes show that implementation quality, information, capability, and institutional context frequently matter as much as the headline policy or technology. Contribution: The article offers an evidence- based framework for local governments and urban service providers that translates the literature into decision principles without claiming primary data that were not collected.
