Migration and urbanization

Explanation:

During the Industrial Revolution, factories were located near concentrations of natural resources and transportation routes. This situation most directly promoted migration and urbanization. Due to the presence of factories, and the ease of transportation, people were able to move into these areas. The influx of people, in turn, contributed to the urbanization process of cities.
