Human Geography 101: Population Geography - Ravensteins Laws of Migration

What This Is

Ravenstein's Laws of Migration are a set of seven principles that explain the patterns and processes of human migration. These laws, developed by German geographer Ernst Georg Ravenstein in the late 19th century, are essential for understanding why people move from one place to another and how these movements shape the world around us. For example, the rapid growth of cities in the United States during the 20th century can be attributed to the push-pull factors described in Ravenstein's Laws, as people moved from rural areas to cities in search of better economic opportunities.

Key Models, Theories & Terms

• Ravenstein's Laws of Migration: A set of seven principles that explain the patterns and processes of human migration, including the push-pull factors, distance decay, and the dominance of short-distance migration.
• Push-Pull Factors: Economic, social, and environmental factors that drive people to move from one place to another, such as poverty, lack of job opportunities, and natural disasters.
• Distance Decay: The principle that the likelihood of migration decreases as the distance between the origin and destination increases.
• Dominance of Short-Distance Migration: The idea that most people migrate short distances, often within their own country or region, rather than long distances.
• Chain Migration: The process by which migrants from a particular origin area move to a new destination area, often following established social networks and family ties.
• Counterurbanization: The movement of people from cities to rural areas, often in search of a more relaxed pace of life and lower costs of living.
• Urbanization: The process by which people move from rural areas to cities, often in search of better economic opportunities and a higher standard of living.
• Migration Streams: The flow of people from one place to another, often influenced by push-pull factors, distance decay, and chain migration.

Step-by-Step Application

1. Identify the push-pull factors driving migration in a given region or country.
2. Analyze the distance decay principle to understand how migration patterns change as distance increases.
3. Determine the dominance of short-distance migration in a given region or country.
4. Examine the role of chain migration in shaping migration patterns.
5. Assess the impact of urbanization and counterurbanization on migration patterns.
6. Use migration streams to visualize the flow of people between different regions or countries.

Common Misconceptions

• Misconception: All migration is permanent.
• Correction: Many migrations are temporary, such as seasonal migration or circular migration, where people move back and forth between their origin and destination areas.
• Example: The seasonal migration of farmers from rural areas to cities in India to work as laborers during the harvest season.
• Misconception: Migration is only driven by economic factors.
• Correction: Social, cultural, and environmental factors also play a significant role in driving migration.
• Example: The migration of people from rural areas to cities in China due to the One-Child Policy, which led to a shortage of labor in rural areas.
• Misconception: Migration is a one-way process.
• Correction: Many migrations are circular or seasonal, with people moving back and forth between their origin and destination areas.
• Example: The circular migration of people from rural areas to cities in the United States to work as laborers during the harvest season.

• 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 migration, such as permanent vs. temporary, economic vs. social, and chain vs. independent migration.
• Model Integration: Use Ravenstein's Laws of Migration to explain migration patterns and processes in a given region or country.
• Contextualization: Be able to place migration patterns and processes within the broader context of economic, social, and environmental factors.

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

Last-Minute Cram Sheet

• Ravenstein's Laws of Migration: 7 principles that explain migration patterns and processes.
• Push-Pull Factors: Economic, social, and environmental factors that drive migration.
• Distance Decay: The principle that migration likelihood decreases with distance.
• Dominance of Short-Distance Migration: Most people migrate short distances.
• Chain Migration: Migrants follow established social networks and family ties.
• Counterurbanization: Movement from cities to rural areas.
• Urbanization: Movement from rural areas to cities.
• Migration Streams: Flow of people between regions or countries.
• Temporary migration is not the same as permanent migration.
• Migration is not only driven by economic factors.
• Migration is not a one-way process.
• Ravenstein's Laws of Migration are not the only model that explains migration patterns and processes.
