Final answer:
The town of Maycomb remained the same size because it was far from urban centers experiencing massive growth.
Step-by-step explanation:
The reason the town of Maycomb remained the same size was because it was far from urban centers experiencing massive growth. In late nineteenth-century America, urban growth was fueled by factors such as industrialization, improved transportation infrastructure, and population shifts. However, Maycomb, as described in the provided passages, was a small town characterized by smoke, iron-foundries, and a lack of urban development. It was far from the bustling cities experiencing massive urban growth, which is why it remained the same size.
