Urban geography studies how cities function, their internal structures, and external influences.
Two main subfields:
Systems of cities: Focuses on where cities are located, their functions, and how they connect regionally and globally.
Internal cities: Examines land use, transportation, segregation, architecture, and development within cities.
Urban areas are nucleated (having a core) and depend on nonagricultural jobs.
City vs. Town:
Towns are smaller and less complex than cities but still have business centers.
Cities include Central Business Districts (CBDs) and are usually surrounded by suburbs.
Suburbs: Residential areas near cities that rely on them economically but have their own governments.
Urbanized areas: Continuous city development where political boundaries are mostly imaginary.
Metropolitan Areas: A large functional unit, often including multiple urban areas.
Metropolitan Statistical Area (MSA): A city of at least 50,000 people plus surrounding counties.
Micropolitan Statistical Area: Smaller version with 10,000–50,000 people and surrounding dependent counties.
Hamlet: Smallest cluster of homes with basic services (e.g., a gas station).
Village: Larger, with more specialized businesses.
Town: More functional specialization (e.g., banks, schools, libraries) and an economic hinterland (dependent rural areas).
City: Larger population, clear CBD, and surrounding suburbs.
Megalopolis: Multiple cities merged together, e.g., Bosnywash (Boston to Washington, D.C.).
Large size: Urban residents know fewer people personally compared to rural areas.
High density:
Leads to job specialization, competition for space, and higher property values.
Can cause social inequality as wealthier groups dominate certain areas.
Social heterogeneity:
Cities attract diverse populations with unique cultures, lifestyles, and professions.
Urban areas offer anonymity but may also lead to isolation and loneliness.
Cities develop in response to human needs and activities, influenced by political, economic, and cultural factors.
Geography plays a key role:
Political: A settlement chosen as a capital can grow into a major city.
Economic: Cities near harbors or trade routes expand through commerce.
Cultural: Some cities grow due to their artistic, educational, or religious importance.
Prehistoric Era (before 10,000 years ago): No permanent settlements.
Neolithic Revolution (~10,000 years ago): Agriculture led to permanent villages.
Early Cities (~3000 B.C.E.):
Irrigation & surplus farming → Job specialization.
Emergence of social inequality → Larger houses and landholdings.
Governments formed to organize resources and build infrastructure.
Formative Era (4000–2000 B.C.E.): States and urban centers emerged in major river valleys:
Egypt (Nile River)
Mesopotamia (Tigris & Euphrates Rivers)
Indus Valley Civilization (Harappa, Mohenjo-Daro)
China (Huang He River)
Aegean Civilization (Greek forerunners)
Ancient cities were strategically located near rivers, fertile land, and trade routes.
Governments controlled food supply, taxes, and security (walls for defense).
Key urban functions:
Political Centers – Capitals of early states.
Religious Centers – Temples, shrines, priests.
Economic Hubs – Markets, trade networks.
Educational Centers – Teachers, philosophers.
Population Limits: Ancient cities typically housed 10,000–15,000 people due to limits in food storage and distribution.
Greek City-States (~2500 years ago): Self-governing communities (e.g., Athens, first city to reach 100,000 people).
Roman Empire (~2nd century C.E.):
Rome grew to 250,000+ people.
Extensive road and sea networks connected cities across Europe, North Africa, and the Middle East.
