Human Geography 101: Economic Geography - Industrial Geography Webers Least Cost Theory Transportation Labor Agglomeration

What This Is

Industrial geography is the study of how industries and economic activities are distributed across space. It examines the factors that influence the location of industries, such as transportation costs, labor availability, and agglomeration economies. Understanding industrial geography is crucial for understanding why some cities thrive while others decline, and how economic activities shape the environment and human societies. For example, the growth of the automotive industry in Detroit, Michigan, led to the development of a sprawling metropolis with a strong manufacturing sector, while the decline of the industry led to widespread deindustrialization and urban decay.

Key Models, Theories & Terms

• Weber's Least Cost Theory: A theory that explains the location of industries based on the least expensive transportation costs, labor costs, and raw materials. For example, the textile industry in North Carolina, USA, is located near ports to take advantage of cheap transportation costs.
• Agglomeration Economies: The benefits that industries gain from being located near other industries, such as shared labor pools, specialized services, and knowledge spillovers. For example, Silicon Valley in California, USA, is home to a high concentration of tech companies that benefit from each other's expertise and innovation.
• Transportation Costs: The costs associated with moving goods and people from one place to another. For example, the Panama Canal reduced transportation costs between the Atlantic and Pacific Oceans, making it easier to trade goods between Asia and the Americas.
• Labor Costs: The costs associated with hiring and retaining workers. For example, the low labor costs in China have made it an attractive location for manufacturing industries.
• Location Quotient (LQ): A statistical measure that compares the proportion of a particular industry in a region to the proportion of that industry in the national economy. For example, an LQ of 2 for the automotive industry in Michigan, USA, indicates that the industry is twice as concentrated in Michigan as it is in the national economy.
• Industrial Complex: A group of related industries that are located in close proximity to each other. For example, the aerospace industry in Los Angeles, California, USA, is part of a larger industrial complex that includes defense contractors, engineering firms, and logistics providers.
• Branch Plant Economy: An economy that is dominated by branch plants, which are satellite factories that produce goods for a parent company. For example, the branch plant economy in the southern United States is characterized by a high concentration of factories that produce goods for companies based in other regions.
• Core-Periphery Model: A model that describes the relationship between a core region, which is a region with high levels of economic development and industrialization, and a periphery region, which is a region with lower levels of economic development and industrialization. For example, the core-periphery model can be applied to the relationship between the United States and Mexico, where the United States is the core region and Mexico is the periphery region.

Step-by-Step Application

1. Identify the dominant industry in a region and explain how it is influenced by transportation costs, labor costs, and agglomeration economies.
2. Use the Location Quotient (LQ) to compare the concentration of a particular industry in a region to the national average.
3. Describe the characteristics of an industrial complex and explain how it contributes to the economic development of a region.
4. Identify the types of industries that are typically found in a branch plant economy and explain how they contribute to the economic development of a region.
5. Apply the core-periphery model to a real-world example, such as the relationship between the United States and Mexico.

Common Misconceptions

• Misconception: All industries are equally influenced by transportation costs, labor costs, and agglomeration economies.
• Correction: Different industries are influenced by different factors, and the relative importance of these factors can vary depending on the industry and the region.
• Example: The textile industry is heavily influenced by transportation costs, while the software industry is heavily influenced by agglomeration economies.
• Misconception: Branch plant economies are always dominated by low-skilled, low-wage jobs.
• Correction: Branch plant economies can include a range of industries, from manufacturing to services, and can provide a range of job opportunities, from low-skilled to high-skilled.
• Example: The branch plant economy in the southern United States includes a range of industries, from automotive manufacturing to software development.
• Misconception: The core-periphery model is only applicable to the relationship between developed and developing countries.
• Correction: The core-periphery model can be applied to a range of relationships, including the relationship between different regions within a country.
• Example: The core-periphery model can be applied to the relationship between the northeastern United States and the southern United States, where the northeastern United States is the core region and the southern United States is the periphery region.

AP Exam / Free-Response Tips

• FRQ Task Verbs: Identify, describe, explain, compare, and analyze are common task verbs on the AP Human Geography exam.
• Tricky Distinctions: Be able to distinguish between different types of industries, such as manufacturing and services, and be able to explain how they contribute to the economic development of a region.
• Model Integration: Be able to integrate different models, such as the core-periphery model and the branch plant economy, into your essays to explain complex geographic phenomena.
• Example: In an essay question that asks you to explain the economic development of a region, you might use the core-periphery model to explain the relationship between the core region and the periphery region, and the branch plant economy to explain the types of industries that are found in the region.

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 circular migration, and one likely urban model that describes its structure is the Burgess concentric zone model.

Explanation: Circular migration is a type of migration where workers move from rural areas to urban areas for temporary work and then return to their rural homes. The Burgess concentric zone model is a model that describes the structure of a city as a series of concentric zones, with the most affluent residents living in the innermost zone and the least affluent residents living in the outermost zone.
