What term describes the urbanisation process in suburbs due to the construction of apartments and services?

The term that accurately describes the urbanisation process in suburbs due to the construction of apartments and services is the urbanisation of suburbs. This process involves the transformation of suburban areas from primarily residential spaces to more integrated urban environments, where residential buildings, commercial services, and amenities are developed. This development often leads to increased population density in these areas as they become more appealing places to live due to greater access to services and infrastructure.

Urban sprawl refers to the uncontrolled expansion of urban areas into the surrounding countryside, typically characterized by low-density development. This does not specifically address the process of enhancing urban characteristics within existing suburbs. Suburban decay refers to the decline of suburban areas, often due to economic factors and disinvestment, leading to a decrease in population and services, which is the opposite of urbanisation. Lastly, rural-urban migration encompasses the movement of people from rural areas to urban centers in search of better opportunities, not specifically related to the development within suburban settings. Therefore, the urbanisation of suburbs is the most precise term for this particular phenomenon.
