The key impact of the Industrial Revolution on urbanization was the massive migration of people from rural areas to cities. As factories emerged and industry expanded, jobs were created that drew individuals and families seeking better economic opportunities. This shift led to rapid urban growth, transforming societies from agrarian to industrialized. Cities became centers of production and innovation, but they also faced challenges, including overcrowding, inadequate housing, sanitation issues, and pollution. The demographic changes initiated by the Industrial Revolution fundamentally reshaped labor dynamics and influenced social structures, setting the stage for modern urban life.
