What led to the massive migration of people from forms to cities?

The massive migration from rural areas to cities, often referred to as urbanization, was largely driven by industrialization in the 19th and 20th centuries. As factories and industries developed, they created numerous job opportunities that attracted people seeking better economic prospects. Additionally, advancements in technology and transportation made urban living more accessible and appealing. Social factors, such as the desire for improved living standards and access to education and healthcare, further fueled this migration trend.
