2023 T3 Flashcards
Immigration
Entering another country and making it the person’s permanent residence
Emigration
Leaving a country to permanently settle in a foreign country
Migration
movement of people form one place to another with the intentions of settling permanently or temporarily, at a new location
Labour migration
Migration for the main purpose of employment
Refugee migration
Leaving a country due to persecution, war, or natural disasters.
population growth
natural increase in the number of people in the population due to fertility, mortality and migration
The one child policy
A policy developed by governments which aimed to manage population growth
An increase of densely populated areas in China mean access to resources became limited, and were no longer able to sustain and support communities (1979)
Social issues with one child policy
decreased quality of life, decreased birth rate, gender imbalance, below replacement level fertility, unregistered children
environmental issues of one child policy
less resources being used, less population, no direct impacts to the environment
economic impacts of one child policy
ageing population, financial pressures
Demographic impacts of one child policy
Overview of population geography
Memorised..
The increase in the human population in the last half centuary is unprecedented; and nearly all the growth is occuring in developing countries.
Demography
the study of statistics such as births, deaths, income, or the incidence of disease, which illustrate the changing structure of human populations.
population growth infleunces
fertility, mortality
others: increasing life expectancy or morbidity
Issues arising from the changing size and distrubution of population
Economic
Rent Can Bring Wally’s Dividends
Resources: scarcer, prices rise
Congested: living conditions, quality of life, disease
Braindrain: the skilled migrate
Welfare: increased need
Dependants: population dependant, economic strain
Issues arising from the changing size and distrubution of population
Social
Risking The Soccer Score Can Give Points
Resource Tension: social, ethnic, political, economic inequaity,
Shortages: transboundary conflict for resources
Stresses Crime: density increases antisocial, suicide
Government Planning: pressure to control size, social planning
Issues arising from the changing size and distrubution of population
Environmental
Cici Will Do Whatever For Senior Prefect
Carbon Dioxide: richest consume more, production increases
Waste: 30% up since 1975, developed nations
Desertification: declining water tables, famine, social unrest, migration
Water: distrbution towards oceans, seage, destruction of fish, development of beaches
Forest: shrinking, demands for wood and paper, industrial world
Soils: last 50 years, 17% degraded
population size
the number of individuals in a population
population composition
different characteristics within a population that can describe the population
e.g. age, ethnicity
Population growth rates
annual average rate of change of population size during a specific period
population distribution
the pattern in which a population is spread over an area
population density
the number of people per specific area
mortality
the number of deaths occuring in a population
fertility
the number of live births occuring in a population
replamcement fertility rate
population exactly replaces itself from one generation to another
natural increase
calculation
crude birth rate – crude death rate
Neollithic revolution
how did it lead to population growth over time
Started dominating nature, agriculture, animal husbandry emerged
Developments facilitated sedentarization of the population
Freed up workforce for other jobs (related to crafts)
Population increase in the neolithic revolution
by 300 million
Industrial revolution
how did it lead to population growth over time
Medical, scientific and economic advances led to this exponential growth
Increase in quality of life from food security, use of technology, education, medical advances,
Clean water, immunisations, refrigerators, low infant mortality,
Technology allowed pregnancies to occur in any situation
Conceiving difficulties, infertility treatments, high risk pregnancies are possible, premature babies use technology to keep alive, children diseases
Technology helping farming techniques, more food for more people, ship food to distant locations using technologies, refrigerators to preserve food
Industrial revolution, life expectancy, child mortaltiy
number of children in China 50s and India 70s
When babies started living till 50s, families had more
Early 1900s most European and American families had 6-8 surviving siblings (China in 1950s-60s, India in 70s to 80s)
Immunisations and vaccinations stopped babies from dying from diseases like Cholera, dysentery, smallpox, measles, influenza and food poisoning
Patterns in population distrbubtion and density
stats
80% of population live in developing regions
In 2020, Asia housed 60% of world’s population 7.8 billion
Eastern and South-Eastern Asia, the most populous region, comprised 30%, 2.3 billion people
2nd largest region, Central and Southern Asia, 2 billion people in 2020, 1.4 million in India
Population density

linear logarithmic scales/graphs
The measures/conditions behind measuring fertility
The mother must:
They experience exact current age-specific fertility rates through lifetime
Live from birth until end of reproductive life
Obtained by summing single year age specific rates at given time
Factors that effect fertility/birth rate
Social
Access to contraceptives,
education –> higher literacy rate= improved knowledge of birth control
access to abortion rights, medical provisions,
nutrition –>,
children in labor force –> asset for labor, farming practices, collection of water
religion –>resitrctions from birth control, demand high fertility
status and role of women –> attitudes to child bearing, marriage, alternative family structures,
family size preference
Factors that effect fertility/birth rate
econonmic
employment oppurnities –> marry later, less children, casualisation,
cost of children –> seen as econonimic assets in LEDCs, workers on land for income, education and childcare expenses
Role of women –> participation in workforce, chnaging structure, attitudes, two income families
Factors that effect fertility/birth rate
environmental
famine
Natural disaster
Harsh conditions
mortality measures
definitions of 3, death, infant mortality, life expectancy at birth
Death rate (crude): number of deaths/1000
infant mortality rate: the number of deaths of infants/1000 births (below 1y)
Life expectancy at birth: the average number of additiona years a person would live if current mortality trends were to continue
Facots that affect life expectancy
social
Access to healthcare (immunisation, antibiotics, insecticides)
Quality of life
Diseases
Lifestyle
Nutritional improvements
Standards of personal hygiene, effluent disposal (sanititsation)
Access to safe drinking water
Education (awareness of health)
Factors that affect life expectancy
economic
Income, occupation (lifestyle), working conditions,
Factors that affect life expectancy

Air quality
Natural disasters
Population profiles

Shape: curved pyramid
Developing country
High birth and death rate
fertility above replacement level
Short life expectancy
Poor access to medical facilties, anitation, nutrition, low levels of education
Less working population (young population)
Low disposable income (spent on children), low quality of life
Expansive population

Longer lifespan
High retirement rate
Smaller workforce
Strain on health services
Constricting poplation
Demographic transition theory
refers to the transition from high birth and death rates to lower birth and death rates as a county develops from a pre-industrial to an industrialised economic system. With increased development comes an increase in population, followed by stability
Stage 1
Demographic transition theory
Birth rates an death rates flucuate at high levels, resulting in low population growth rates
High fluctuating
Stage 2
Demographic transition theory
Birth rates remain high but death rates fall rapidly, results in rapidly growing population
Early expanding
Stage 3
Demographic transition theory
birth rates now fall rapidly wile death rates also continue to fall but at a slower rate. The net result is slowly increasing population.
Late expanding
Stage 4
Demographic transition theory
Birth rates and death rates remain low, fluctuating slightly to givea steady population
Low flucuating
Stage 5
Demographic transition theory
Birth rates fall below death rates to give a declining population. There is evidence of his in some countries in Western Europe.
Declining
Stats of ageing population
population pyrmid
Average of mid-late 30s
Replacement level TFR
stat
2.1 children per woman
Growth patterns in developing and developed countries
amount of people in certain ages
Developing nations have 80% of population
31% of the world population is under 15 years old
Predictions about population growth
Further growth in youth population is inevitable (developing world)
Explosive growth rates will be followed by significant slowdown (stabilising b&d rates and development becomes widespread, Stage 5)
Overpopulation
situation where the size of a population has overwhelmed the ability of human and natural systems to meet their needs
Reasons for falting population growth in past
Poverty, environmental degradation, political instability in 50s-80s led effects to reduce growth rates
Population planning
the practice of artificially altering the rate of growth of a human population
Population policies/planning can provide greater control of reproduction while others are more authoritative in their approach (one child policy)
tipping point
occurs when the human resource extraction exceeds the ability of the natural environment to regenerate and meet future population needs
Fertility spatial patterns
stats, countries and developing and developed nations
Highest birth rates are in Africa and SW Africa
Lowest birth rates are in Europe, Australia, NZ, Japan, Canada, USA (high standard of living), peoples material well being increases, tend to have fewer children (exception is China)
China is low due to strict population control policy
Low rates found in Western and European developed countries due to higher standard of education
High rates in Africa due to low standard of education on contraception
Rates of feritliy falling below replacement level for MEDCs
Spatial patterns for mortality
Low mortality in Western and European developed countries → high standard f living
High mortality rates in African countries
High rates in countries facing persecution, middle eastern conflict in afghanisation, pakistan, syria, etc
Spatial patterns of life expectancy
Diseases developing countries like HIV epidemic set back life expectancy
Global disparities in length of life remain large
LEDCs have lower life expectancy due to prevalence of diseases, access to education that could increase health awareness, high mortality rates, low quality health care,
Access to health care, quality of life in certain nations
