Final answer:
Urbanization is the process that describes the movement of people from rural to urban areas, often in search of better economic opportunities and living standards, and it is exemplified by the increasing proportion of populations living in cities.
Step-by-step explanation:
Humans tend to live in cities, which yields access to natural and economic resources. This is an example of urbanization. Urbanization refers to the process through which rural areas become urban and involves the migration of people from the countryside to cities. This phenomenon is closely linked to industrialization, as people move in search of better economic opportunities, often in factories and other urban enterprises. The shift towards living in cities is reinforced by the desire for improved living standards and access to better services and amenities. Over time, as societies industrialize, more emphasis is placed on urban living, leading to a majority of populations residing in urban areas, as seen in many developed countries today.
