Metropolitan Dynamics: Specialization and Spatial Segregation
Metropolitan Specialization and Urban Displacement
The specialization of functions within the metropolitan area has created large shopping centers, entertainment venues, and residences tailored for different social classes. This specialization causes continuous displacement of residents between their homes, workplaces, commercial sites, and leisure areas.
Land Use and the Rise of Second Homes
Another factor that has increased land use is the rise of the second home. Although the second residence is a finished product, it is often not consumed by the rural households that rehabilitated abandoned villages or houses during the years 1960–1970.
Functional Organization of the Modern City
Core Urban Functions
The basic functions of a city traditionally include:
- Administration and Service
- Commercial
- Residential
- Industrial
The Shift to Tertiary Services
Currently, tertiary functions dominate cities. Primary activities are residual, and industrial activities have largely moved to industrial parks or technology parks located outside the main urban centers.
Cities as Regional Service Providers
Cities now act as major service providers for their metropolitan area, province, or region. Many cities serve as centers for commercial, cultural, educational, legal, and business activities. If the city is the capital of a state or autonomous province, it also serves as the central hub for public administration services.
Understanding Spatial Segregation
The residential function occurs in areas with very different characteristics, including the old historic center, urban expansion zones, suburban areas, and the outskirts of cities.
Economic Disparity and Residential Patterns
Within cities, significant economic differences exist among inhabitants. This disparity usually leads to the separation of the population into districts based on economic status—a phenomenon known as spatial segregation.
Degradation of Historic Urban Centers
In many towns, the historic center suffers significant degradation due to aging buildings and infrastructure. Consequently, populations with greater economic resources often leave, while those with fewer resources (who are often elderly) remain.
Population Dynamics and Migration
Empty residences are frequently occupied by migrants, transient populations, or marginalized individuals. If the administration does not intervene to rehabilitate and consolidate these old towns, they become populated by an aging demographic and many poor immigrants.
Ethnic and Cultural Segregation
Furthermore, immigrant populations tend to concentrate in specific streets or neighborhoods. This results in segregation that is not only economic but also cultural and ethnic.
