Final answer:
Most of Pennsylvania's counties are not classified as urban in population; the correct answer is false, reflecting the mix of urban, suburban, and rural areas in the state.
Step-by-step explanation:
The question asks whether most of Pennsylvania's counties are classified as "urban" in population. This question pertains to the level of urbanization within the state of Pennsylvania. Considering the information provided about urbanization trends in the United States, while urbanization has been a growing trend since the 1950s, it is not accurate to categorize most of Pennsylvania's counties as urban. Much of the population does live in metropolitan or suburban areas, but not all counties would be classified as strictly urban. Therefore, the correct answer to whether most of Pennsylvania's counties are classified as urban in population is false. Most of Pennsylvania's counties are classified as "urban" in population. False.
In the late 1800s, the population of the United States grew rapidly, with much of this growth taking place in urban areas. However, this does not necessarily mean that most counties in Pennsylvania are urban. Urban areas are typically defined by the census as having a population of twenty-five hundred people or more, and while Pennsylvania has several large cities, it also has many rural and suburban areas.
