About this book:

*Cities of Change* explores the urban evolution of New York, Mexico City, São Paulo, and Buenos Aires from the late nineteenth century to the digital age. By framing these metropolises as "laboratories of modernity," the book examines how plural pathways of growth have reshaped social life. It moves beyond traditional top-down narratives to prioritize "street-level" urbanism, analyzing how migration, housing, labor, and infrastructure are negotiated through a constant dialogue between formal planning and informal practices.

The text details the development of specific housing typologies—tenements, *vecindades*, *cortiços*, and *conventillos*—illustrating how density and scarcity forced residents to invent architectures of survival. It argues that informality is not a sign of urban failure but a foundational grammar of growth that sustains economies, mobility, and community resilience when official systems falter. Central to the narrative is the role of the resident—from street vendors and domestic workers to activists and artists—who actively produces the city through everyday innovation and social negotiation.

The book further addresses the challenges of the twenty-first century, including environmental risk, climate resilience, and the rise of digital urbanism. It highlights how racial, ethnic, and gendered hierarchies are embedded in the urban fabric, affecting everything from policing to the "care economy." By comparing these four distinct yet interrelated cities, the work reveals that urban modernity is an unfinished and contested experiment. Ultimately, it calls for governance and planning that acknowledge informality and prioritize equity, recognizing that the most resilient urban solutions often emerge from the grassroots.

What You'll Find Inside:

• Comparative analysis of New York, Mexico City, São Paulo, and Buenos Aires as laboratories revealing diverse pathways of modern urbanization in the Americas
• The pervasive role of informality in housing, labor, and urban economies as adaptive responses to scarcity and regulatory gaps
• How migration waves—both international and internal—have fundamentally reshaped urban demographics, labor markets, and cultural landscapes
• The constant negotiation between formal urban planning and everyday practices of residents in shaping city life
• Interconnected challenges of housing affordability, health outcomes, environmental risks, and social inequality across metropolitan areas

Who's It For:

This book is designed for urban planners seeking policy tools that recognize informality as integral to urban life, historians interested in comparative narratives that connect local developments to hemispheric patterns, and general readers wanting to understand four major American cities through the lens of everyday urban experiences. It will particularly benefit those studying urbanization, migration, housing policy, and social inequality in metropolitan contexts. The comparative approach makes it valuable for academics and practitioners working on urban issues across the Americas and beyond.
