Major internal migrations include rural to urban migration, westward expansion in the US and Brazil, and northward movement in Australia and Canada. In the US, migration has been westward, southward to the Sunbelt, and from urban to rural areas in the 1970s. Pew Center maps show changing internal migration patterns over time between regions. Urbanization involves both increasing urban populations and the percentage living in cities, which is usually higher in more developed countries though Latin America and the Middle East have grown to similar levels. Rapid urbanization in less developed countries is driven by rural to urban migration due to economic and environmental factors as well as population growth and access to information.

Internal migration in China went through three main phases: phase 1 saw the implementation of the Hukou system in 1958 to strictly control rural-urban migration; phase 2 from 1980 encouraged short-distance migration for small businesses but long-distance migration still occurred, creating a "floating population" of 100 million by 1990; and phase 3 introduced temporary residence permits in the late 1980s to fuel industrialization and allow massive migration surges to major eastern cities while still withholding full Hukou rights.MIGRATION-RAFI

The document discusses various causes and types of human migration. It notes that historically migration has been driven by needs for food, shelter and safety, but now also includes job relocation and overpopulation. Rural-urban migration is common in developing countries as people move to cities for more opportunities, though often settle in slums. Migration can have both positive and negative effects on populations and cultures through changes in demographics and mixing of groups. Push factors driving migration include lack of resources and jobs, while pull factors attracting migration include potential work and improved standards of living.Internal migration lesson 5

Internal migration in Indonesia involves the transmigration program which aims to redistribute population from densely populated Java to less populated outer islands. The government provides assistance to migrants moving from source areas like Java, Bali, and Madura to destination areas such as South Sumatra, Sulawesi, Kalimantan, and Irian Jaya. While this reduces population pressure on Java, it also displaces indigenous groups and changes the ethnic composition of destination areas.Migration

Rural-urban and peripheral-core region migration are most common, though rural-rural migration occurs in developing nations for reasons like employment, family, and marriage. Migration between urban areas involves step migration up the hierarchy as migrants' knowledge and finances increase, alongside other urban-urban moves for education and jobs. Reasons for relocation can be viewed at macro, meso, and micro scales focusing on socioeconomics, origin/destination factors, and individual circumstances, respectively.Migration

Migration refers to the movement of people between locations. It has been influenced by social, economic, military and political factors over time and has contributed to increasing diversity in countries like the US. While most migration occurs over relatively small distances, factors like violence, lack of opportunities, and search for better lives push people to migrate longer distances. Common types of migration include rural-to-urban and movements influenced by seasonal labor demands. The causes and impacts of migration are complex and affect both originating and destination populations.Migration and Types of Migrations involving World migration Pattern

1. Migration involves the movement of people across boundaries and is one of three components of population change, along with births and deaths. It is difficult to measure, model, and forecast compared to fertility and mortality.
2. Migrations can be internal within a country or region, or international across country borders. They can be voluntary or involuntary, and people who migrate are either immigrants or emigrants depending on their departure and destination points.
3. Migrations are selective based on factors like age, sex, family size, occupation, race, and education level. Young adults tend to migrate more than other age groups for jobs, while married people migrate less than unmarried people. Men also tend to migrate more than women.AS Level Human Geography - Migration of Population

Migration can be categorized based on several factors. It can be internal within a country or international between countries. It can be forced due to issues like persecution or natural disasters, or voluntary due to reasons like employment or family. There are also models that try to explain migration patterns, such as Newton's Gravity Model which relates migration numbers to population sizes and distances, and Lee's Model which considers personal factors in migration decisions. Migration impacts places both demographically through population changes, and socially and economically through consequences like changing communities or reducing population pressures.Migration pdf

This document discusses various types and causes of human migration. It defines migration as a permanent change in residence and distinguishes between emigration, immigration, and internal migration. Key factors that influence migration decisions include economic, political, environmental, cultural, and technological conditions. Migrants weigh "push" factors that induce them to leave their home against "pull" factors that attract them to potential destinations. Forced migration occurs when people have no choice but to flee and become refugees or internally displaced persons. Historic examples of large-scale migrations discussed include African slaves to the Americas, Europeans to North America/South America, and internal migration within countries like the US and Russia.Migration in Pakistan

Migration patterns in Pakistan include movements from northern mountainous regions, western highlands, and eastern deserts to the more populous Indus plains. Key drivers of migration have been the development of Punjab's canal colonies in the early 1900s, partition between India and Pakistan in 1947, and several Indo-Pakistani wars which caused waves of refugees. More recently, conflict in Afghanistan has led to many Afghan refugees settling in Pakistan, while illegal immigration from Bangladesh and internal rural-to-urban migration have also significantly impacted Pakistani society and infrastructure. Remittances from international emigration, especially to the Gulf and UK, now constitute a major part of Pakistan's economy.Migration

Migration refers to the movement of people between locations to live or work. There are two types of migration - voluntary and forced. Voluntary migration occurs when people choose to move to places with better economic opportunities or quality of life, while forced migration happens when people are compelled to relocate due to issues like wars or natural disasters. Countries experience benefits and drawbacks from both emigration, where their citizens leave, and immigration, where foreign citizens enter. Benefits include economic gains from remittances or filling jobs locals don't want, while drawbacks involve fewer taxpayers or pressures on housing and social services.Karachi- The City of Migrants

It discusses how population is unevenly spread worldwide and defines key terms like population distribution, density, and growth. Population distribution is influenced by physical factors like relief, climate, drainage, and soils as well as human factors like agriculture, mining, and urbanization. Population density is calculated by dividing the total population by the land area. Countries in the Caribbean have varying densities, with the highest in Bermuda and lowest in Guyana. Choropleth maps can be used to display differences in density across areas. World population has grown significantly from 1.65 billion in 1900 to over 7 billion currently, influenced by birth rates, death rates, and fertility rates.More Related Content

This document discusses different types of migration including rural-urban migration, seasonal migration, planned migration, and involuntary migration. It provides details on each type, including common causes, examples, and potential consequences for areas that migrants leave and arrive in, as well as consequences for migrants themselves. Rural-urban migration is driven by population growth and lack of opportunity in rural areas, pushing young males to cities. Planned migration includes Indonesia's transmigration program to relocate people from overpopulated islands like Java to less populated outer islands, with mixed results. Involuntary migration refers to forced migration of refugees fleeing conflict, persecution, or environmental disasters.What is urbanisation?

The document discusses urbanization, defining it as a process where an increasing proportion of the population lives in towns and cities. There are two main causes of urbanization: rural-urban migration and natural increase. Rural-urban migration occurs as people move from rural areas to cities due to push factors like lack of land and poverty in rural areas, and pull factors like employment opportunities and quality of life improvements in urban areas. Natural increase also contributes to urbanization as a high birth rate combined with improved healthcare in cities leads to urban populations growing independently of migration. The document concludes by showing which parts of the world have the highest and lowest levels of urbanization.CHAPTER 12- LAND-USE PLANNING. Environmental Science

Here are the answers to the questions:
1. Migration means the movement of people from one place to another. The main types of migration are:
- Emigration: Leaving one's country to settle in another.
- Immigration: Entering a new country to settle permanently.
- Transmigration: Moving from a densely populated area to a less populated one.

This document discusses refugees and internally displaced persons (IDPs). It defines a refugee as someone outside their country of nationality due to fear of persecution. There are currently 11.5 million refugees worldwide. IDPs are unable to leave their country but cannot access protection services. There are 25 million IDPs facing an uncertain future. Canada accepts around 25,000 refugees per year and the US accepts around 75,000. Emerging issues impacting refugees include increasing populations, conflicts over land and resources, poverty, and tensions leading to more displacement as less developed countries become reluctant to accept refugees. Forced displacement can perpetuate political instability.Global ecological problems

Urbanization is the growth of urban areas due to global population changes. The UN projects that half the world's population will live in urban areas by 2008. Urbanization is closely linked to modernization, industrialization, and sociological changes. It describes both the proportion of people living in urban areas and the rate of increase of urban populations over time. As more people move from rural to urban areas in search of jobs and opportunities, global urban growth is rapid, especially in developing countries and Asia/Africa. This urbanization leads to environmental effects like urban heat islands and increased pollution in cities.Urban Sprawl In America

Urban sprawl occurs when cities expand outward into rural areas, consuming land. This document summarizes some key causes and impacts of urban sprawl in the United States. Population growth is a major driver, as people seek more affordable housing and space in the suburbs. However, urban sprawl leads to increased pollution, traffic, and loss of agricultural land. It also strains infrastructure and finances as governments must expand services further out. The document recommends controlling population growth and changing attitudes about development to limit unsustainable urban sprawl.aia greenbuilding 7.20.15

Global challenges like urbanization, inequality, and climate change threaten communities. By 2030, 6 in 10 people will live in cities facing housing shortages and increased costs of $16 trillion to address. Climate change will require $75-100 billion annually for developing countries to adapt. Inequality between neighborhoods in major cities has grown significantly. However, citizen-led grassroots movements and design assistance teams providing pro bono expertise have helped many communities implement revitalization strategies. Examples in Provincetown, Austin, and Tampa transitioned areas from car-oriented to more connected, sustainable, and equitable places.2.3 Notes - Population Patterns

There are 39 million foreign-born individuals in the United States, accounting for 11.7% of the total population. Over half of foreign-born individuals originate from Mexico and Central America, while a quarter come from Asia. It is estimated there are between 11-20 million undocumented immigrants in the US, with the largest numbers and proportions coming from Mexico. The report provides data on foreign-born and undocumented immigrant populations in the US from the Pew Hispanic Center.Migration And Mobility Pt3

International migration since the 16th century has consisted of two main streams: labor migration and refugee flows. The largest migration in history was approximately 60 million Europeans emigrating from Europe beginning in the 16th century. The United States experienced major periods of immigration between the 17th-19th centuries, from 1820-1860, 1860-1890, 1890-1910, and since 1965 to present day. Each period saw shifts in the countries and regions that immigrants emigrated from, including Germany, Ireland, China, Italy, and Mexico at different times. Legislation such as the National Origins Act of 1924 and Immigration and Nationality Act of 1965 altered immigration patterns and levels.Migration And Mobility Pt2

This document discusses different theories of migration including individual decision making and structural factors that influence migration patterns. It describes push factors that drive people to leave their home areas, such as lack of jobs or conflict, and pull factors that attract migrants to new areas like jobs or amenities. The document also discusses how certain groups are more likely to migrate than others based on attributes like age, marital status, gender and occupation. Finally, it outlines some of the demographic, socioeconomic and political consequences of migration for both sending and receiving regions.Migration And Mobility Pt1

The document discusses different types of human migration and mobility. It defines migration as a move between places, usually across political boundaries, that involves a permanent change in residence. Different types of migration discussed include internal migration within a country, international migration between countries, primitive migration of groups unable to cope with environmental changes, group or mass migration of clans and tribes, free individual migration, restricted migration with government controls, impelled migration where people have some choice in leaving, and forced migration where people have no choice or power over leaving.
Epidemiological Transition
Epidemiological Transitionkdjw
油
The document discusses the epidemiologic transition, which describes the transition of major causes of death from infectious diseases to chronic and degenerative diseases as populations adopt behaviors associated with economic development and improved living standards. It describes three models of transition - the classic Western model over 200 years, an accelerated model in places like Japan and Eastern Europe, and a delayed model in most low-income developing countries since WWII. The transition is accompanied by changes in mortality and morbidity patterns, as well as demographic changes as fertility declines and populations age.Mortality
Mortalitykdjw
油
The document discusses key concepts related to mortality rates and life expectancy. It begins by defining mortality and some of the determinants that influence death rates. It then provides data on crude death rates globally and by region/country. Subsequent sections cover age-sex specific death rates, differences in mortality trends between more and less developed countries, and factors that have contributed to changes in mortality over time such as public health interventions and medical advances.Infant Mortality
Infant Mortalitykdjw

This document discusses infant mortality rates around the world. It defines infant mortality as deaths of children under age 1. The world infant mortality rate in 2008 was 49 per 1000 live births, while rates were lower in more developed countries (6 per 1000) and higher in less developed and least developed countries (54 and 85 per 1000, respectively). Infant mortality is an important indicator of overall health conditions and levels of development within a country. Many infant deaths are preventable through improved medical care and interventions.Population Composition & Structure - Food Supply
Population Composition & Structure - Food Supplykdjw
油
The document discusses population composition and food production trends around the world. It notes that Africa, Asia, and Latin America currently have the youngest populations, while Europe has the oldest. In the US, about 1 in 8 Americans are elderly, a proportion that has been increasing since 1900 due to high birth rates in the late 19th/early 20th century and declining mortality. Over two-thirds of global cropland is used to grow cereals and grains, which provide half of global caloric intake. While food production doubled between 1950-1990, production per capita has declined since 1984. China accounts for a large portion of food output but also population in developing regions. Strategies to increase yields include fertilizers, irrigation, andPopulation Composition & Structure
Population Composition & Structurekdjw
油
The document discusses key elements of population composition and structure, including sex ratio and age structure. It defines sex ratio as the number of males per 100 females in a population. Age structure is analyzed using population pyramids that show cohorts in 5-year age groups. The postwar US baby boom from 1946 to 1964 significantly increased births, affecting age structure. Analysis of population composition and structure is important for understanding future population growth patterns and the dependency ratio.Introduction To Population Geography
Introduction To Population Geographykdjw
油
The document discusses various topics in population geography and demography. It defines population geography as the study of population phenomena and patterns in different parts of the world, while demography is defined as the study of human population characteristics. Population geography is concerned with the spatial expression of demographic processes and the study of human population composition, growth, distribution, and migratory movements, with a focus on the last two. Geographers focus on space and demographers focus on time. The document also discusses censuses and vital records, and how geographers use spatial analysis and place-based reasoning to solve problems relating to human-environment relations such as political redistricting and monitoring population growth and decline.Internal Migration Online
