Grade 10 Geography - Understanding Population Movements: Migration Types, Causes, and Effects

Population Movements - Grade 10 Geography (CAPS) – Term 3 - (From the FOCUS Grade 10 Geography Textbook) This presentation explores Population Movements, the capstone subtopic in the Population strand of the Grade 10 CAPS Geography curriculum (Term 3). Designed for high school learners and educators, it breaks migration down into three core sections: the different types of population movement, the causes and effects driving migration, and the specific effects of migration on South Africa. Learners will explore key migration concepts including international migration, emigration, immigration, regional migration, rural-urban migration, urbanisation, and counter (urban-rural) migration, along with the distinction between voluntary and forced migration, and permanent versus semi-permanent movement. The deck applies the push–pull model of migration to explain why people leave rural areas (drought, unemployment, poor services) for urban centres (better jobs, education, infrastructure) and examines the real-world consequences of this movement, including rural depopulation and the growth of informal settlements. Featured case studies include: The 1994 Rwandan genocide and the resulting forced international migration of over two million refugees South Africa's emigration and immigration trends from 1980–2003, including the impact of apartheid-era exile and post-1994 migration patterns Global migration research findings from Stellenbosch University and the French National Institute of Demographics (INED) By the end of this presentation, learners will be able to classify different types of population movement, analyse push and pull factors behind migration decisions, and evaluate the social, economic and demographic impacts of migration on both sending and receiving areas. Keywords: Grade 10 Geography, CAPS curriculum, population movements, migration types, push-pull factors, rural-urban migration, urbanisation, Rwanda genocide case study, South Africa migration, emigration, immigration, geography revision, high school geography

Population Movements Why do people move, and what happens when they do? Grade 10 Term 3 Week 8 By Mr. Ismail
Lesson Objectives By the end of this lesson, you should be able to: 01 Define migration and correctly identify and classify at least 6 kinds of population movement. 02 Analyse the causes and effects of population movements by correctly sorting at least 5 factors into push or pull categories using the push–pull model. 03 Evaluate migration's impact on South Africa to identify at least 2 trends and justify 2 advantages and 2 disadvantages of migration for SA.
Lesson Roadmap 01 Part 1: Types of Population Movement What is migration, and what forms does it take? 02 Part 2: Causes and Effects of Population Movement Why do people move, and what happens as a result? 03 Part 3: The Effects of Migration Focus on South Africa Key questions: What is migration? What are the different kinds of population movement? What causes people to migrate? How does migration affect South Africa?
CHAPTER 1 OF 3 Part 1: Types of Population Movement/Migration Exploring the many forms that human movement takes — across borders, within regions, and over time.
What is Migration? • Migration: the movement of people so that they change their place of residence • Migration types differ according to: the reasons for movement, the time involved, and the distance involved • Historical context: By 1900, more than a million people were leaving Europe every year, trying to improve their quality of life Geo fact: Birds, mammals, insects and fish also migrate to feed and breed — the Arctic tern migrates the greatest distance of any animal, over 70,000 km a year between the Arctic and Antarctic
Kinds of Migration: Crossing Borders International Migration Movement of people across a country's borders (e.g. South Africa to New Zealand). Usually long-distance and costly, though exceptions exist (e.g. walking from Zimbabwe to South Africa). Can be short-term or permanent. Emigration Movement of people OUT of their home country — e.g. a South African emigrating to Australia. Immigration Movement of people INTO a new country of residence — e.g. immigrating from Zimbabwe to South Africa.
Kinds of Migration: Within Regions and Countries Regional Migration Movement within a region, e.g. within southern Africa/SADC — usually country to country, seeking work. Rural-Urban Migration Movement from rural areas to towns and cities, often within the same country. Urbanisation The result of rural-urban migration — more and more people living in urban places. Urban-Rural Migration Movement from towns/cities back to rural areas — called "counter migration" because it goes against the normal flow.
How Long Do People Migrate For? The duration of migration varies enormously — from a lifetime to a single daily commute. Permanent Migration People change their place of residence forever. Semi-Permanent Migration People change residence for a set period — a year or two (e.g. teaching English in South Korea), or seasonally (e.g. farm work in summer months). Daily Migration (Commuting) Regular movement to and from a place of work each day.
Voluntary vs Forced Migration Voluntary Migration A person chooses freely to migrate — driven by the desire for better opportunities, lifestyle, or environment. Forced Migration A person is forced to migrate, often because of religious or political factors — they have no real choice but to leave. What does forced international political migration look like in practice?
CASE STUDY Hutus in Rwanda: Forced International Political Migration • Rwanda: small central African country; 2010 population ~10.5 million • Two main ethnic groups: Hutus (~84%) and Tutsis (~15%); decades of conflict between them • During six weeks in 1994, groups of Hutus killed about 800,000 Tutsis and Hutus married to Tutsis — roughly a tenth of Rwanda's population died • Genocide: the deliberate killing of people from a certain ethnic group or nation • Over 2 million people fled to refugee camps on the border with Zaire (now the DRC); hundreds died from cholera and other diseases • By 1996, many refugees had returned — partly because Tutsis in Zaire began killing Hutus in revenge
Globalisation and Migration What is Globalisation? The integration and connection of countries — boundaries between them are becoming less important. Globalisation Favours Migration More people are moving within their own country and across international borders than ever before. The Global Workforce Geographers speak of a "global workforce": people who move around the world to work for multinational corporations or for themselves. 1. 2. 3.
CHAPTER 2 OF 3 Part 2: Causes and Effects of Population Movement Why do people migrate, and what are the consequences for people, places, and societies? https://youtu.be/4QrUegs-kUs?si=1Bjh_UNSChzWBXEu
Why Do People Migrate? Movement requires effort, so people always migrate for a reason: Economic Searching for a job, or a job that pays more money Political & Security Escaping political oppression, wars, chaos, conflict, or crime Religious Escaping religious persecution, prosecution or conflict Social To be with family members or friends Health & Quality of Life Cleaner environment, better healthcare, housing, services or schools Geo fact: In 2010 there were 200 million international migrants who voluntarily chose to live in another country
The Push-Pull Model of Migration A simple way to understand rural-to-urban migration — this movement drives urbanisation and rural depopulation. ⬅➡ PUSH Factors (Rural Origin) • Drought and famine • No jobs, no money • Poor schools and hospitals • No electricity or basic services • Boredom and lack of opportunity Result: Rural depopulation PULL Factors (Urban Destination) ➡⬅ • Better job prospects • Better services and infrastructure • "Bright lights" — nightlife and entertainment • Better education opportunities Result: Urbanisation Urban: Pull Migration Rural: Push
Consequence in Focus: Informal Settlements Rural-urban migration in South Africa has led to the growth of informal settlements in urban areas. Discussion: What problems might newly arrived migrants face living in an informal settlement? Lack of proper healthcare Lack of proper housing Lack of proper education Crime Poor hygiene and sanitation
Global Urbanisation Trend 50%+ Urban Population Worldwide, more people now live in urban areas than rural areas 75% By 2030 An estimated 75% of the Earth's population will be urbanised This global shift is driven largely by rural-urban migration — the same push-pull forces at work in South Africa are reshaping cities worldwide.
What Research Tells Us About Migration Source: Stellenbosch University 60%+ Within Developing World About 60% of migration happens between developing countries, or between developed countries — not South to North 50% Within Own Region Close to half of all migrants move within their own region of the world Women Migrants 50% About half of all migrants are women0 3% African Cross-Border Only 3% of Africans live in a country different from where they were born Most migrants move within the borders of their own country, rather than across international borders. Migrants are usually successful people in their new countries.
Global Migration Flows (2005–2010) Source: French National Institute of Demographics (INED) Key Insight Most migration flows occur within hemispheres, with the largest cross-hemisphere flow going South to North (62 million people). The North-to-South flow is dramatically smaller at just 14 million — less than a quarter of the South-to-North movement. • 61 million migrated within Southern Hemisphere countries • 53 million migrated within Northern Hemisphere countries • 62 million migrated from South to North • 14 million migrated from North to South

CHAPTER 3 OF 3 Part 3: The Effects of Migration South Africa Focus How does migration shape South Africa's people, places, and economy?
Different Effects for Different Groups Different types of migration have different effects on: The Migrants Themselves Their livelihoods, identity, and wellbeing Areas They Leave (Origin) Depopulation, loss of workforce, family separation Areas They Arrive In (Destination) Population growth, pressure on services, cultural change
Urbanisation and Rural Depopulation in South Africa • In 2011, 38% of all people in South Africa lived in rural areas • Many rural areas lie in the former homelands created under apartheid — neglected, underdeveloped and densely populated • Despite improvements: high unemployment, widespread poverty, and a lack of basic services (water, electricity, sanitation, education, healthcare, housing) • This creates a push factor, forcing people toward the pull factors of urban areas — even though urban life doesn't always deliver the better life migrants expect • Depopulation: a decline in the total number of people living in an area — often only children and older people remain • Suggested solution: uplift and develop rural areas
A Growing Counter-Trend: Urban to Rural Push Factors FROM Urban Centres High cost of city living, stress, pollution, and congestion are driving some people away from cities. The Technology Enabler Technological advances such as the internet and email now allow more people to live and work in the rural countryside — making counter- migration increasingly viable. There is a growing trend of movement in the opposite direction — from cities to rural areas — known as urban-rural migration or counter migration.
South Africa's Emigration and Immigration History 1 Apartheid Era Thousands of South Africans lived in exile rather than live under apartheid — a form of forced emigration driven by political oppression. 2 After 1990 The government unbanned organisations such as the ANC, PAC and Azapo. Most exiled migrants returned to South Africa. 3 Today: Emigration Many South Africans emigrate in search of better jobs or a better life — the so-called "brain drain". 4 Today: Immigration Many people immigrate to South Africa, especially from other African countries, because SA has the strongest economy and highest standard of living on the continent.
Reading the Data: SA Migration, 1980–2003 Source: SA Institute of Race Relations • Sharp immigration spike in the early 1980s (peaking near 45,000 in 1983), then a steep drop by 1986 • A second, smaller immigration peak around 1990 • Emigration relatively stable through the 1980s–90s, with a peak around 1987 • Both lines dip to their lowest points around the late 1990s/2000 • Both rise again toward 2003 Note: Data collection ended in 2004 due to the Immigration Act of 2002
Discussion: Interpreting the Trends 1. Early 1980s: South Africa gained far more people than it lost. What historical factors could have attracted people to South Africa then? 2. Late 1980s and late 1990s: South Africa lost more people than it gained. What factors may have encouraged people to leave? 3. Emigration was lowest in the early 1990s while immigration rose. Why might fewer people have emigrated then, and who do you think was immigrating to South Africa during this period? 4. Why might these statistics NOT be a true reflection of exactly who left or entered South Africa? (Consider undocumented migration.)
The Advantages and Disadvantages of Migration on South Africa Considering economic, social, and skills-related impacts. Advantages for SA Disadvantages for SA Emigrants leaving SA  Eases pressure on jobs, housing, and services, since fewer people are competing for these resources.  Can reduce unemployment figures in the short term  Brain drain, South Africa loses skilled workers (e.g. doctors, engineers, teachers) it spent resources training.  Loss of tax revenue and economic productivity as skilled, working-age people leave.  Shrinking workforce in key sectors, which can slow economic growth. Immigrants coming to SA  Brings additional skills and labour, especially in sectors facing shortages (e.g. agriculture, medicine, engineering).  Immigrants often start small businesses, contributing to job creation and the economy.  Adds cultural diversity  Increased pressure on already strained services (housing, healthcare, education) and infrastructure.  Can increase competition for jobs, especially in low-skilled sectors, sometimes fuelling social tension or xenophobia.  Contributes to growth of informal settlements if new arrivals cannot access formal housing.
