Final answer:
Suburbanization is the shift from urban to suburban areas, contributing to the growth of metropolitan areas and overall urbanization. This trend has led to economic prosperity in developed countries and poses a developmental challenge in poorer nations.
Step-by-step explanation:
Suburbanization refers to the population shift from central urban areas into suburbs, resulting in the formation of (sub)urban sprawl. Post-World War II, suburbanization became a significant trend in North America, leading to the growth of metropolitan areas and contributing significantly to urbanization. As the economy develops, agglomeration factors, such as improved transportation, better housing opportunities, and the pursuit for a higher quality of life, have encouraged more people to live in suburban environments around cities. In the United States, suburban areas have seen a steady increase in population density, changing from rural communities to bustling centers of residential and commercial activity. This phenomenon has played a key role in the economic prosperity of many regions, with a high percentage of the country's population now living in these areas.
While suburban growth has been synonymous with prosperity in developed countries, it presents a challenge in developing economies. Urbanization in poorer nations, such as those in Africa, is increasing, but at a slower pace, indicating that managing urban growth is vital for sustainable development. As the trend toward urban life continues, focusing on the growth of suburban spaces becomes essential for socioeconomic planning and infrastructure development.
