Explain urbanization and suburbanization processes and provide examples.

• A. Suburbanization outward spread into surrounding areas; urbanization is growth of urban areas.
• B. Urbanization is growth of urban areas through migration and population increase; suburbanization outward spread into surrounding areas; examples megacities and commuter belts.
• C. Urbanization and suburbanization are identical processes.
• D. Urbanization is rural depopulation.

Answer: (B)

Urbanization is the growth of urban areas as people move from rural regions into cities and as city populations increase, leading to higher density and expanded urban boundaries. Suburbanization is the outward spread of development from the city into surrounding rural or peri-urban areas, creating suburbs and a commuter population connected to the city by transportation networks.

Examples help ground the idea: urbanization shows up in megacities like Tokyo, Mumbai, and Lagos, where the urban footprint expands as millions reside in and around dense city centers. Suburbanization is seen in the rings of suburbs and commuter belts around major cities—around London, around New York City, and around Delhi—where people live in expanding suburban areas while commuting to the core city for work.

The idea here is that these are distinct but related processes: urbanization is about the city growing in place and population, while suburbanization is about development spreading outward from the city into surrounding areas.
