Which of the following is characteristically found within the inner city?

Brownfield sites are areas of land that were previously used for industrial purposes but are now underdeveloped or abandoned. They are commonly found in the inner city, which is often characterized by older, densely populated regions that have undergone significant industrial activity in the past. The presence of brownfield sites in inner-city areas can be traced back to urban decline as industries move out to suburban or peripheral areas, leaving behind former industrial sites.

The redevelopment of these brownfield sites is often targeted in urban regeneration projects since they can be repurposed for residential, commercial, or recreational use, which helps revitalize the inner city. Unlike greenfield sites, which are undeveloped areas usually found in suburban or rural settings, brownfield sites represent opportunities for redevelopment within the established urban fabric. High levels of economic opportunities and high-end residential properties may also be present in parts of the inner city, but they are not as defining of the typical landscape compared to brownfield sites.
