Welcome to Your Geography Journey!
Hello! Today, we are diving into the fascinating world of Internal Migration. This isn't just about moving house; it’s about how millions of people shifting within their own countries change the way our world looks, works, and grows. Whether it’s moving from a quiet farm to a buzzing city or shifting from a cramped city center to a leafy suburb, these movements shape our economy and our society. Don't worry if some of the terms feel new—we will break everything down step-by-step!
1. What is Internal Migration?
Before we start, let’s get our definitions straight. Internal migration is the movement of people from one place to another within the same country. This movement must last for at least one year to be officially counted as "migration" in your syllabus.
Quick Review: Two Key Terms
1. Source Area: The place the person is moving from (the old home).
2. Receiving/Destination Area: The place the person is moving to (the new home).
2. Rural–Urban Migration: Moving to the City
This is the most famous type of internal migration, especially in Low-Income Countries (LICs) and Middle-Income Countries (MICs). It is the movement of people from the countryside (rural) to towns and cities (urban).
Why do people move? (Push and Pull Factors)
Think of it like a magnet. Some things "push" you away from your old home, while others "pull" you toward a new one.
Push Factors (Negative things about the countryside):
• Low wages: Farming often doesn't pay well.
• Lack of services: Few schools, hospitals, or shops.
• Environmental problems: Droughts or floods making farming impossible.
Pull Factors (Attractive things about the city):
• Job opportunities: Factories, offices, and service jobs.
• Better "Bright Lights": This is an analogy for the excitement, entertainment, and better education/healthcare found in cities.
• Perception: People think life will be much easier in the city, even if it’s tough at first.
Impacts of Rural–Urban Migration
When people move, they don't just take their bags; they change the population structure (the age and gender of the people living there).
Impact on the Source Area (The Countryside):
• Ageing Population: It’s usually the young, fit adults who leave. This leaves behind the elderly, who may struggle to work the land.
• Gender Imbalance: In many cultures, men move to cities first, leaving women to run the households.
• Economic Loss: The "brain drain"—the most educated or ambitious people leave.
Impact on the Receiving Area (The City):
• Overcrowding: Cities grow too fast, leading to shanty towns (squatter settlements).
• Pressure on Services: Not enough doctors or school places for everyone.
• Labor Supply: Plenty of workers for new factories and businesses.
Key Takeaway: Rural-urban migration usually makes the rural population older and the urban population younger and more male-dominated initially.
3. Urban–Rural Migration: Heading Back to the Countryside
In High-Income Countries (HICs), we often see the opposite: counter-urbanisation. This is when people move out of the city and into rural villages.
Why leave the city?
• Pollution and Noise: Cities can be stressful and dirty.
• Improved Technology: High-speed internet allows people to work from home (teleworking).
• Retirement: Older people often want a quiet life in a scenic area.
Impacts of Urban–Rural Migration
• Gentrification: Wealthy city people move to villages, buy old cottages, and fix them up. This sounds good, but it makes house prices so high that local young people can't afford to live there anymore!
• Changing Services: The village shop might close because newcomers drive back to the city to go to the supermarket, but new fancy cafes might open.
4. Stepped Migration and the Settlement Hierarchy
Don't worry if this seems tricky at first! Just imagine a ladder. Stepped migration is the idea that people don't always move from a tiny farm to a massive mega-city in one go. Instead, they move in "steps" up the settlement hierarchy.
The Hierarchy Ladder:
1. Isolated Farm/Hamlet (The bottom)
2. Village
3. Small Town
4. Large City
5. Capital City/Metropolis (The top)
Example: A student moves from a village to a small town for high school, then to a large city for university, and finally to the capital city for a high-paying job. This is stepped migration!
5. Urban–Urban and Intra-Urban Movements
Migration doesn't always involve the countryside. Sometimes, it stays within the city limits.
Urban–Urban Migration
This is moving from one city to another city. Usually, this happens for career reasons—for example, a manager being promoted and moving from a branch in Manchester to a headquarters in London.
Intra-Urban Migration
This is moving within the same city. If you move from an apartment in the city center to a house with a garden in the suburbs, that is intra-urban migration.
Causes of Intra-Urban Movement:
• Life-Cycle Changes: When people get married or have children, they need more space (the "pull" of the suburbs).
• Income: As people earn more, they move to "nicer" neighborhoods.
• Urban Renewal: If a city knocks down old, poor-quality housing and builds new apartments, people are forced to move elsewhere.
Did you know? Most people move the shortest distances. You are much more likely to move to the next street than to a city 500 miles away. This is a common pattern in geography!
6. Summary and Common Mistakes
Memory Aid: The "P-P" Rule
Always check your answer for Push (why leave?) and Pull (why arrive?). If you only mention one, you only have half the story!
Common Mistakes to Avoid:
• Confusing Internal with International: Internal is inside the country. If the question asks about internal migration, do not talk about refugees crossing borders or moving to a different country.
• Forgetting "The Why": Don't just say "people move." Explain who is moving (usually the young) and why (jobs, education, lifestyle).
Quick Review Box:
• Rural-Urban: Most common in LICs/MICs; driven by jobs.
• Counter-urbanisation: Moving to the countryside; common in HICs.
• Stepped Migration: Moving up the "ladder" of settlement sizes.
• Intra-urban: Moving within the same city, often due to family size or wealth.
You've got this! Internal migration is all about the stories of people trying to improve their lives. Keep these steps and hierarchies in mind, and you'll do great.
