Challenges of urbanization in the early 20th century?

Urbanization in the early 20th century presented several challenges, including overcrowding, inadequate housing, and poor sanitation, which often led to public health crises. The rapid influx of people into cities strained infrastructure, resulting in traffic congestion and a lack of basic services like clean water and waste disposal. Additionally, social tensions arose from economic disparities and the diverse backgrounds of urban populations, leading to increased crime and unrest. These issues prompted reform movements aimed at improving living conditions and urban planning.
