What was the main cause of urbanization during the Industrial Revolution?

The main cause of urbanization during the Industrial Revolution was an increase in the number of factories. As the Industrial Revolution progressed, many people moved from rural areas to urban centers in search of jobs in the newly established factories. This shift was driven by the demand for labor in industrial settings, which significantly transformed the landscape of cities and led to rapid urban growth. While other factors, like increased farm production and overcrowded living conditions in cities, played roles in this transformation, the establishment of factories was the primary catalyst for urbanization during this period.
