Why did urban populations expand during the industrial revolution hist?

Migration of rural to urban and mass immigration.

The factories were in high demand of workers and immigration aided in this demand. Many people in Europe were leaving due to harsh economic conditions and nationalist movements. These immigrants were in large numbers and flocked to the cities of America.
