What was an effect of urbanization in the early 20th century?

• A. Decrease in factory jobs
• B. Increased population density in cities
• C. Decline in public transportation systems
• D. Expansion of rural agricultural industries

Answer: (B)

Urbanization in the early 20th century led to a significant increase in population density in cities. As people moved from rural areas to urban centers in search of better job opportunities, particularly in industries and factories, cities grew rapidly. This migration resulted in a concentration of people living in urban areas, which often led to overcrowding and the development of new housing structures to accommodate the influx of workers.

The growth of cities also prompted the expansion of infrastructure, such as roads, schools, and public services, to support the increasing population. This period saw profound changes in urban lifestyles, social dynamics, and economic patterns, fundamentally reshaping society at the time. The rise in urban population density was a defining characteristic of this era, influencing everything from labor movements to cultural changes in urban environments.
