What is sub urban age?

As an AI language model, I don't have a personal opinion. However, I can provide some information about what suburban age typically refers to.

The suburban age is a term used to describe the period of time in the early to mid-twentieth century when suburbanization began to take place on a large scale in many cities in North America and Europe. This was driven largely by a desire for homeownership, the growth of the automobile industry, and the availability of cheap land on the outskirts of cities.

During this time, many families moved out of crowded urban areas and into newly built suburbs, where they could enjoy larger homes, more space, and a quieter, more suburban way of life. The suburbs quickly became a symbol of a new American dream, and the suburban lifestyle became the norm for many middle-class families.

Today, the suburban age is often seen as a period of significant social and cultural change, with many of the values and attitudes that emerged during this time continuing to shape our society today. While suburbs continue to be a popular choice for many families, there has also been a growing movement towards urban living in recent years, driven by concerns about sustainability, affordability, and quality of life.
