Arithmetic (crude)
Physiological (nutritional)
Agricultural
terms and concepts to know
Population distribution and density affect political, economic, and social processes, including the provision of services such as medical care
Carrying capacity: the ability of the land to sustain a certain number of people
terms and concepts to know
Patterns of age structure and sex ratio vary across different regions and may be mapped and analyzed at different scales
Population Pyramids: a graphical illustration that shows the distribution of various age groups in a population
→ Predict markets for goods and services (what will a population need based on the age and sex composition?)
terms and concepts to know
Demographic
Fertility
Total Fertility Rate
Mortality
Infant Mortality Rate
Maternal Mortality Rate
Rate of natural increase
Population-doubling time
Demographic Transition Theory- Stage 1
Stage 1: Low Growth
Long-term NIR near 0
Primarily hunting and gathering
8000 B.C.- world’s population increased from 5 million to 800 million.
Agricultural Revolution
Food supplies still unpredictable, war, disease- remained Stage 1
No countries in Stage 1 today
Demographic Transition Theory- Stage 2
High growth!
CDR plummets, CBR remains same, high NIR
1790 A.D.- Industrial Revolution
Industrial technology and agricultural production
Increased wealth = health
1800- North American and
Europe reached Stage 2
1950- Latin America, Africa, Asia
Medical revolution- diffused to LDCs
Immunizations, insecticides, etc.
Demographic Transition Theory- Stage 3
Stage 3: Moderate Growth
CBR drops sharply
modest population growth
North America and Europe in
first half of 20th century
Asia and Latin America in recent years
Most of Africa still in Stage 2
CBR drops due to social customs and economics:
Reaction to low IMR, urban living- not farming families, smaller urban dwellings
Demographic Transition Theory- Stage 4
Stage 4: Low Growth
Zero Population Growth
May occur in CBR is a bit higher than CDR- Why?
ZPG: TFR that results in lack of change in total population over long term- (replacement level of 2.1, unless country has many immigrants)
Social Customs- women in labor force, child care
Lifestyles- birth control, increased leisure and income- entertainment, travel, etc. unsuitable for children
Demographic Transition Theory
Country that has passed all four stages:
Beginning- CBRs and CDRs are high (35-40/1000)
End- CBRs and CDRs are low (10/1000)
Total population is much higher in stage 4 than stage 1
Stage 5: Negative Growth
Negative NIR- deaths exceed births- (E. Europe, Japan, Hong Kong, Singapore, Western Europe)
Contested significance of the Demographic Transition Model:
Not good for establishing population patterns on the periphery (good for analysis of the core)
Industrialization in a peripheral country is often the effort of core countries which can affect population “patterns”
Lower educational opportunities and technology in certain regions of the world
Epidemiological Transition Model
life expectancy | deaths due to Cardiovascular disease | |
---|---|---|
Stage 1: Pestilence and Famine | 35yrs | 5-10% |
Stage 2: Receding Pandemics | 50yrs | 15-35% |
Stage 3: Degenerative and Human Created Diseases | 60yrs | >50% |
Stage 4: Delayed Degenerative | >70yrs | <50% |
Stage 5: Possible Re-emergence of epidemics | N/A | N/A |
terms and concepts to know
Malthusian theory and its critiques are used to analyze population change and its consequences.
Malthus’s Theory
Too many people + not enough food = **DEATH (**we will reach carrying capacity)
Solutions?
Neo-Malthusians
Situation is MUCH worse
Malthus didn’t plan for LDCs to move on the DTM
Running out of all resources, not just food!
Critiques
Possibilism!
Technology has allowed us to produce more food / resources
Large population increases production
Esther Boserup:
people will learn to use their land more intensively in order to meet food production needs
the question of overpopulation
Thomas Robert Malthus- (1766-1834)
An Essay on the Principle of Population, 1798
Food and Sex drive humans
Background: revolutionary time period
agriculture and industry caused loss of jobs
“surplus of unnecessary workers”
displaced farmers a burden in cities- poor laws
he believed power of population growth is greater than Earth’s ability to create food.
We will reach Carrying Capacity!
Neo-Malthusians
call for strict demographic controls
Believe the situation is worse than Malthus thought…
Malthus failed to predict LDCs moving into stage 2 due to medical revolution.
Population is growing faster than economic growth, resources available
Population is not only outgrowing food, but other resources as well.
clean air, fuel, sustainable farm land
Malthus’ Critics
possibilism! Supply of resources is not fixed!
Larger population increases production
more brain power= more solutions
bigger militaries = power
Marxists: no relationship btwn population and hunger-
blame on unjust political/social institutions
Friedrich Engels (Marxist): plenty of food if equally shared equally- blame on capitalism
Esther Boserup:
people will learn to use their land more intensively in order to meet food production needs
terms and concepts to know
Explain the intent and effects of various population and immigration policies on population size and composition.
Types of population policies include those that promote or discourage population growth, such as pronatalist, antinatalist, and immigration policies.
Pro-Natalists
Promote human reproduction
financial incentives, maternity leave
Anti-Natalists
Concerned with limiting population growth
China’s “one child policy”
NonMom Summit Oct 2015
China’s One-Child Policy (removed in 2015)
little emperors, precious snowflakes
imbalanced sex ratios (start at 2:04)
India
human rights issue: forced sterilizations
imbalanced sex ratios
Kenya
family planning, education by community members
Japan, Germany, Russia, Singapore, Denmark
financial incentives, nationalism
terms and concepts to know
Explain how the changing role of females has demographic consequences in different parts of the world.
changing social values and access to education, employment, health care, and contraception have reduced fertility rates in most parts of the world.
changing s*ocial, economic, and political roles* for females have influenced patterns of fertility, mortality, and migration, as illustrated by Ravenstein’s laws of migration.
terms and concepts to know
Explain the causes and consequences of an aging population.
Population aging is determined by birth and death rates and life expectancy.
An aging population has political, social, and economic consequences, including the dependency ratio.
Ratio of a number of live births in a single year for every thousand people in the population (without looking at age-specific groups or cohorts which is limiting)
Higher levels of fertility at the periphery (especially Sub-Saharan Africa)
Crude Death Rate (CDR): ratio of the number of deaths in one year to every thousand people in the population
Why would the crude death rate be higher in an MDC than in a LDC?
Natural increase/decrease Rate (NIR): difference between CBR and CDR
Infant mortality rate (IMR): annual number of deaths of infants less than one year of age compared to 1,000 live births for that same year
Average number of years an infant newborn can expect to live. In 2016: 78.7 years
men: 76; women: 81
white: 78.9; African American:75.1
Can be affected by epidemics
Medical geography: a sub area of the discipline that specializes in understanding the spatial aspects of health and illness
Measure of the economic impact of the young and old on the more economically productive members of the population
The more dependents you have per workers, the worse the economic situation for your country
terms and concepts
Migration is commonly divided into push factors and pull factors.
Push/pull factors and intervening opportunities/obstacles can be cultural, demographic, economic, environmental, or political
**__Voluntary Migration: __**migrant has chosen to move
Usually consists of 2 main aspects
Away from someplace – push factors (usually negative)
Toward someplace – pull factors (usually positive)
Economic opportunities / Lack of jobs
Social push and pull factors
People often migrate when they experience discrimination and persecution because of their ethnicity, race, gender, or religion.
Political push and pull factors
People who oppose the policies of the government often migrate because they face persecution, arrest, and discrimination
Environmental push and pull factors
People often migrate to escape harm from natural disasters, drought, and other unfavorable conditions
Demographic Push and Pull Factors
Some countries are unbalanced demographically
Gender – young adult might not find someone to marry
Young population – country faces risk of overpopulation
Intervening Obstacles
Barriers that make reaching their desired destination more difficult
Economic – a migrant lacks enough money to reach a destination
Social – a migrant gets married to someone who lives along the migration route and settles in that person’s community
Political – a migrant cannot get a visa needed to enter a country
Environmental – a migrant cannot cross sea, desert, or mountain range
terms and concepts to know
Forced migration
Slavery and events that produce refugees, internally displaced persons, and asylum seekers.
Voluntary Migration
Types include transnational, transhumance, internal, chain, step, guest worker, and rural-to urban
Forced migration is a permanent movement, usually compelled by cultural factors
Involves internally displaced persons, refugees, and asylum seekers
Displaced Persons and Refugees
An internally displaced person (IDP) has been forced to migrate for similar political reasons as a refugee but has not migrated across an international border
A refugee is someone who is forced to migrate from his or her home country and cannot return for fear of persecution because of his or her race, religion, nationality, membership in a social group, or political opinion.
Montreal turns stadium into welcome centre for asylum seekers from US
Largest numbers of refugees in 2014 were forced to migrate from Afghanistan and from Syria because of continuing civil wars.
Neighboring countries received most of them – Pakistan and Iran from Afghanistan and Lebanon and Turkey from Syria
An asylum seeker is someone who has migrated to another country in hope of being recognized as a refugee
Voluntary migration is a permanent movement undertaken by choice
May be transnational, internal, chain, step, and rural to urban
Transnational – across international borders
Internal – within international borders
Chain – following relatives, members of your ethnic group
Step – series of small, less extreme moves
Rural to urban
terms and concepts to know
Migration has political, economic, and cultural effects
Effects of Colonization
European culture spread across the globe
Indigenous populations and their cultures were nearly wiped out by European diseases and replaced by European cultures
European languages and Christianity dominated the Western Hemisphere
In contrast, in Asia and Africa, people shared the same diseases carried by Europeans
People kept their traditional languages and religions
The diffusion (spread) of goods and ideas went both ways between Europeans and their colonies – Columbian Exchange
Forced Migration
Major result of European expansion was the Atlantic Slave Trade
Largest example in history of forced migration – people do not choose to relocate, but do so under threat of violence
15th-19th centuries – 12.5 million Africans were captured, enslaved, and forcibly moved from Africa to North America, the Caribbean, and South America
Effects on Countries of Origin
Positive
Relief from overcrowding
Zelinsky’s Migration Transition Model (Stage 2/3 → Stage 4/5)
Negative
If working-age people leave – population is skewed toward elderly and children, creating a dependency ratio problem and may undercut the traditional family structure (Ex: China’s rural to urban migration – largest migration within a country in history)
Brain drain – about 11% of Africans with advanced degrees live in the U.S., Europe, or other developed countries
Effects on Receiving Countries
Immigrants make cultural contributions to their new countries (new foods, words, forms of entertainment and religious traditions)
Tend to be highly motivated to get an education, work hard, and succeed
Often open small businesses that are service-oriented (nail salons, restaurants, etc.) but almost 200 of the 500 largest businesses in the world were started by immigrants or their children
Remittances, money sent to family members still in the country of origin, account for nearly 40% of the income of some small countries
Leading countries of origin: United States and Saudi Arabia
Leading countries as recipients: India and China
