Human Geography 101: Introduction to Human Geography - Spatial Perspective Space Place Region Location Distance Scale

What This Is: Spatial Perspective

Spatial perspective is the way we understand and analyze the relationships between people, places, and environments. It involves considering the spatial dimensions of human activities, such as migration, trade, and communication, and how they shape the world around us. For example, the growth of New York's Little Italy can be explained by the chain migration of Italian immigrants who settled in the city, attracted by job opportunities and existing social networks.

Key Models, Theories & Terms

• Central Place Theory (CPT): A model explaining the distribution of settlements and services in a region, with larger cities serving as hubs for smaller towns and villages. Application: The spacing of towns in Iowa, USA, follows CPT, with larger cities like Des Moines and Cedar Rapids serving as central places.
• Von Thünen's Model of Agricultural Land Use: A model explaining the distribution of agricultural activities around a city, with different activities located at varying distances from the city center based on transportation costs. Application: The model explains why dairy farms are often located near cities, while grain farms are farther away.
• Demographic Transition Model (DTM): A five-stage model linking population growth to economic development, with high birth rates and death rates in Stage 1 and low birth rates and death rates in Stage 4. Application: The DTM explains why some countries, like Niger, still have high birth rates, while others, like Japan, have low birth rates.
• Rank-Size Rule: A model explaining the distribution of city sizes in a region, with larger cities serving as hubs for smaller cities. Application: The rule applies to many regions, including the United States, where larger cities like New York and Los Angeles serve as hubs for smaller cities.
• Growth Pole Theory: A model explaining the growth of cities and regions, with growth poles serving as centers of economic activity and innovation. Application: The growth of cities like Silicon Valley and Boston can be explained by their role as growth poles, attracting entrepreneurs and businesses.
• Urban Hierarchy Model: A model explaining the distribution of cities in a region, with larger cities serving as hubs for smaller cities. Application: The model applies to many regions, including the United States, where larger cities like New York and Los Angeles serve as hubs for smaller cities.
• Distance Decay: A concept explaining how the intensity of interactions between places decreases with distance. Application: Distance decay explains why trade and communication between cities decrease as distance increases.
• Scale: A concept explaining the level of detail or scope of analysis, with larger scales showing broader patterns and smaller scales showing more detailed patterns. Application: Scale is important in analyzing the impact of climate change on local communities versus global patterns.
• Location: A concept explaining the position of a place in relation to other places, with absolute location referring to a place's physical location and relative location referring to a place's position in relation to other places. Application: Location is important in analyzing the impact of transportation infrastructure on economic development.
• Place: A concept explaining the unique characteristics and identity of a place, including its culture, history, and physical environment. Application: Place is important in analyzing the impact of gentrification on local communities.

Step-by-Step Application

1. Read a population pyramid to identify the demographic characteristics of a region, including birth rates, death rates, and population growth.
2. Identify the type of diffusion in a cultural practice, such as the spread of Christianity or the adoption of a new technology.
3. Draw the Burgess concentric zone model for a city, with different zones representing different land uses and socioeconomic characteristics.
4. Analyze a map to identify the location and distribution of cities, roads, and other features, and explain their impact on economic development and human migration.
5. Use the Demographic Transition Model to explain the population growth and economic development of a country or region.
6. Apply the Rank-Size Rule to explain the distribution of city sizes in a region.

Common Misconceptions

• Misconception: All migration is permanent.
• Correction: Migration can be temporary or permanent, and many people move back and forth between their home and destination countries.
• Example: Seasonal migration of workers from Mexico to the United States.
• Misconception: GDP per capita is the same as standard of living.
• Correction: GDP per capita is a measure of economic output, while standard of living refers to the quality of life and well-being of individuals.
• Example: A country with a high GDP per capita may still have a low standard of living if its wealth is concentrated among a small elite.
• Misconception: The Rank-Size Rule applies to every country.
• Correction: The rule applies to many regions, but not all countries, and there are many exceptions and variations.
• Example: The rule does not apply to countries with a single dominant city, such as Singapore.

AP Exam / Free-Response Tips

• FRQ task verbs: Identify, describe, explain, compare, and analyze.
• Tricky distinctions: Ethnicity vs. nationality, site vs. situation, centripetal vs. centrifugal forces.
• Integrating models: Use models to explain and analyze real-world phenomena, and be sure to provide evidence and examples to support your arguments.
• Scoring: FRQs are scored on the basis of content, organization, and writing quality.

Quick Practice Scenario

A megacity in a developing country grows rapidly as rural residents move in for factory jobs. Identify the dominant migration pattern and one likely urban model that describes its structure.

Answer: The dominant migration pattern is rural-to-urban migration, and one likely urban model is the Burgess concentric zone model.

Explanation: The Burgess model explains the growth of cities as a series of concentric zones, with different land uses and socioeconomic characteristics in each zone.
