What Defines a City?
The Evolution of Human Settlements
- Humans transitioned from living in caves and huts to constructing permanent homes, leading to the formation of villages and towns.
- As populations grew due to continuous access to food and water, the first cities began to emerge.
Understanding Cities
- A significant portion of the global population has historically lived in rural areas focused on agriculture; cities were often small, unsafe, and faced hygiene issues.
- By the early 20th century, only 14% of the world’s population resided in cities; this figure rose dramatically over time.
- In 2007, urban populations surpassed rural ones for the first time at 50.1%, with current estimates suggesting that by 2050, 68% will live in cities.
Criteria for Defining a City
- Numerical Criterion: A city is typically defined as having at least 10,000 inhabitants (in Spain).
- Economic Activity: Cities primarily engage in secondary (industry) and tertiary (services) economic activities, unlike rural areas which focus on primary activities like agriculture.
- Functions of a City: Must serve as residential hubs, government centers, commercial distribution points, cultural institutions (e.g., universities), and tourist attractions. Springfield is used as an example to illustrate these functions.
Urban Hierarchies and Dependencies
- If a settlement does not meet city criteria but serves administrative or cultural roles dependent on a nearby city, it may be classified as a town instead.
- Larger cities influence smaller ones regionally or nationally; examples include Madrid influencing Spanish regions or New York impacting globally.
Metropolitan Areas
- An area metropolitan encompasses surrounding satellite cities that depend on a major city for resources and services; they can function as dormitory or industrial towns.
Challenges Faced by Modern Cities
- Urban areas face significant challenges such as resource consumption (water/energy), waste generation (sewage/trash), air pollution from vehicles/industries, social inequality between affluent neighborhoods and impoverished zones, and high housing costs pushing low-income residents outward.
