Answer :

Final answer:

Urban workers experienced a significant increase in numbers during the Industrial Revolution in America due to the transition to factory work and influx of new immigrants seeking better opportunities.


Explanation:

Urban workers saw the most significant increase in numbers as a result of the Industrial Revolution in America. The influx of unskilled laborers into factories, including men, women, and children, contributed to the expansion of the urban workforce during this period.

The working class, predominantly hourly wage laborers in factories, formed a crucial part of the growing urban population, transitioning from agricultural duties to factory work. This shift led to the rise of the middle class, comprising owners and supervisors of industrialized establishments.

Factory owners benefited from easy labor replacement due to a continuous influx of new immigrants seeking better opportunities in the United States. Although working conditions were unsafe and wages were low, the industrialization period saw a surge in urban worker populations.
