The statistics in this table illustrate population changes associated with —the rise of industrialism in the United States

a prolonged food shortage in the United States
a lengthy war over disputed territory
Answer:
the rise of industrialism in the United States
Explanation:
As we can see in the table shown above, the cities presented show a progressive population growth, showing larger numbers as the information progresses. This period of progressive population growth was introduced in American cities during the period of rise of industrialism in the country. That's because industrialism was the time when living conditions got better for the American population, allowing birth rates to get higher and death rates to get lower, promoting great population growth.
