POPULATION = the total number of inhabitants of a particular country.
POPULATION GROWTH = the rate of change in the size of a country's population.
In the THINK AHEAD above, you should have realised:
New enrollments act like the birth rate.
Students leaving or graduating act like the death rate.
The net flow of expat students acts like net migration.
In other words:
Δ Enrollment = Δ Newbs - Δ leavers + Δ NET-expat enrollment
Δ POP = Δ BIRTHS - Δ DEATHS + Δ NET-MIGRATION
The BIRTH RATE measures the number of live births per thousand of the population in a year. lt is measured by dividing the total number of births in a country by the population size, expressed per thousand of the population.
The TOTAL FERTILITY RATE (TFR) measures the average number of children that a woman would have over her childbearing years (i.e. age 15-49), based on current birth trends.
A fertility rate of 2.1 children per woman is considered to be the minimum replacement fertility rate for a stable population (the number of children that the average woman must have to replace the existing population). Fertility rates >2 children indicate a growing population and vice-versa
The DEATH RATE measures the number of deaths per thousand of the population in a year. It is measured by dividing the total number of deaths in a country by the population size, expressed per thousand of the population.
"Mr. Bounous immigrated to HK."
IMMIGRATION: When people ENTER a country to live and to work.
"Mr. Bounous emigrated from UK."
EMIGRATION: When people LEAVE a country to work and live abroad.
"Remember, 'rate' is in actual numbers not as a %"
Note: This question ignores net migration: "When BR>DR population rises"
"Despite the BR>DR, this positive increase might be offset by a negative net migration."
"Net emigration is another way of saying negative net migration, so if more 20-40-year-olds are leaving, it means the working population will be getting older on average."
"There are 20 x 1000, so this means 20 x +10 extra so the popuation will grow by 200 to 20200"
"Why would people be more/less willing to have children?"
"Why would people be more/less likely to die?"
"Why would people be more/less willing to enter/leave a country?"
--LIFE EXPECTANCY--
LIFE EXPECTANCY measures the number of years an average person in the country is expected to live.
"How does life expectancy impact population?"
Clearly if fewer people die young, then more people survive to older ages meaning the death rate will be lower.
--GOVERNMENT POLICY--
"How does government policy impact population?"
Through regulation, incentives, etc., the government can try to discourage or encourage people to have more or fewer children, impacting the birth rate.
--TO DISCOURAGE POPULATION GROWTH--
--TO ENCOURAGE POPULATION GROWTH--
--COST OF RAISING CHILDREN--
"How does the cost of having children impact the pop?"
Clearly the higher the financial burden of raising children, the lower the birth/fertility rate.
--AVAILABILITY OF BIRTH CONTROL--
"How does birth control impact population?"
The availability (prevalence) of contraception appears to strongly correlate with the fertility rate, suggesting the greater prevalence the lower the birth rate.
--WOMAN IN THE LABOUR FORCE--
"How do women in the LF impact the population?"
As more women enter the workforce, women have less time to raise children, and the fertility rate appears to lower, though its impact in sub-Saharan Africa seem mininal.
--THE INFANT MORTALITY RATE--
THE INFANT MORTALITY RATE refers to the number of infant deaths for every 1,000 live births.
"How does the infant-mortality rate impact the pop?"
"Looking at the data below, it is clear to see that the higher the infant mortality rate, the higher the fertility rate; in other words, as the chance of survival increases, people choose to have fewer babies, lowering the birth rate. Can you think why this is?"
Tip: Google 'The replacement/insurance effect'
--CHILDCARE AFFORDABILITY--
"How does affordable childcare impact the pop?"
"Looking at the articles below, it is clear to see that the more unaffordable childcare is, the lower the fertility rate; as couples not only see it as a large extra cost, but given the need for two incomes, it makes it impossible to be a 'working mom.'" "Now you can see how 'essential' the 'domestic helpers' are to Hong Kong's economy"
--LEVEL OF HEALTH EDUCATION--
"How does health education impact the pop?"
"When we talk about health education, we are focused on knowledge and understanding about how to live longer and reduce the death rate. Examples include educating parents on how to look after their children's health, e.g., breastfeeding, vaccinations..., preventing diseases by educating people about hygiene (handwashing, sanitation), safe sex (preventing HIV/AIDS, STIs), mosquito control (malaria, dengue), etc., as well as how to manage chronic diseases in aging populations by educating them on diet, exercise, smoking cessation, and medication compliance, which reduces deaths from heart disease, stroke, and diabetes.
etc... so many...
--SOCIO-POLITICAL ISSUES--
-PUSH FACTORS
1. Issues in Countries of Origin (PUSH Factors)
Armed Conflict & Violence: War, civil strife, and generalized violence are the most direct and powerful drivers of forced migration and refugee flows.
Political Persecution & Lack of Rights: Authoritarian regimes, suppression of dissent, persecution of ethnic/religious minorities, and lack of political freedoms force many to seek asylum.
State Failure & Corruption: Collapse of governance, extreme corruption, and lawlessness make life untenable and destroy economic opportunities, leading to both skilled and unskilled emigration.
Human Rights Abuses: Systematic abuses, including those based on gender, sexuality, or belief, drive vulnerable groups to flee.
Economic Mismanagement: While economic, hyperinflation, or collapsed public services often have political roots (e.g., sanctions, failed policies).
-PULL FACTORS
Immigration & Asylum Policies: This is the most direct political lever. Points-based systems, family reunification rules, asylum recognition rates, and quotas directly determine who can enter and stay.
Political Rhetoric & Public Sentiment: Nativist, populist, or xenophobic political discourse can create a "hostile environment," discouraging potential migrants even if legal pathways exist. Conversely, inclusive rhetoric and narratives can act as a pull factor.
Integration Policies: Access to language classes, recognition of foreign qualifications, and anti-discrimination laws affect the long-term settlement of migrants and their ability to contribute, influencing both future flows and the retention of existing migrants.
Welfare State & Access to Public Services: Debates over migrants' access to healthcare, housing, and social benefits are politically charged. Restrictive policies may deter some, while generous systems may attract others (a common point of political contention).
Labor Market Regulations: Policies on work visas for skilled and unskilled workers, and sectors with recognized shortages, directly channel economic migration.
--AGE OF POPULATION--
--VUCA-RELATED--
The VOLATILITY, UNCERTAINTY, COMPLEXITY, and AMBIGUITY of the world has led to greater anxiety about the future causing people to delay or even cancel their plans to have children.
From what we have read above regarding the factors that determine differences in population we can infer that a DEVELOPING NATION is likely to have:
A YOUNG POPULATION due to LOWER LIFE EXPECTANCY AND HIGHER DEATH RATE due to POOR HEALTHCARE/NUTRITION
A HIGH BIRTH/FERTILITY RATE due to the LOWER COST OF RAISING CHILDREN, as well as the NEED FOR CHILDREN TO SUPPORT THEIR PARENTS later in life.
Suffer from NET EMIGRATION due to RELATIVELY LOWER LIVING STANDARDS.
etc...
From what we have read above regarding the factors that determine differences in population we can infer that a DEVELOPED NATION is likely to have:
AN OLDER POPULATION due to HIGHER LIFE EXPECTANCY and LOWER DEATH RATE, due to GOOD HEALTHCARE & NUTRITION
A LOW BIRTH/FERTILITY RATE due to the HIGH COST OF RAISING CHILDREN as well as NO REQUIREMENT FOR CHILDREN TO SUPPORT THEIR PARENTS later in life.
Suffer from NET IMMIGRATION due to RELATIVELY HIGHER LIVING STANDARDS.
--'OPTIMUM POPULATION'--
OPTIMUM POPULATION refers to the NUMBER OF PEOPLE that, when combined with the economy's stock of other factors of production, produces the MAXIMUM OUTPUT PER HEAD.
We can see that as the population grows, the labour force grows and the GDP PER HEAD INITIALLY RISES as the RESOURCES PER WORKER ARE ABUNDANT, and division of labour, specialization, and economies of scale are eventually fully exploited, increasing productivity and efficiency to reap the highest gains at the OPTIMUM GDP PER HEAD.
However, as the population grows, more and more workers are added, and the AVAILABLE RESOURCES AVAILABLE REACH THEIR PRODUCTIVE PEAKS, and resources are not used as productively and efficiently as before and may suffer from depletion, and unsustainable overuse, thus GDP PER HEAD STARTS TO FALL.
UNDERPOPULATED refers to the scenario when there is SURPLUS of unused resources relative to the number of workers.
If population grows and BELOW optimal
(+) Improve the use of resources
(+) Larger market => economies of scale
(+) Extra demand, stimulates investment
(+) larger labour force
OVERPOPULATED refers to the scenario when there is SHORTAGE of resources relative to the number of workers.
If population grows and ABOVE optimal
(-) Food, housing, welfare shortages
(-) Environmental impact eg more waste
(-) More unemployment => welfare spending
LOWER the COST (Incl: OPP-COST) OF HAVING CHILDREN:
FINANCIAL INCENTIVES such as child benefit which will help people to afford to have children/may enable a parent to stay at home to look after children or pay for childcare when both parents work.
SUBSIDISED HEALTHCARE & EDUCATION, will lower the cost of having children.
PROVISION of NEW/BETTER HOUSING provides security for families, making them more willing to have children.
PROVISION of SUBSIDISED/FREE FERTILITY TREATMENTS to help couples have children.
NEW LAWS ON MATERNITY/PATERNITY RIGHTS & PAY which protect working women who are pregnant/giving parents paid leave, making it illegal to discriminate.
RAISE THE COST OF CONTRACEPTION./ABORTION:
REDUCTION in the PROVISION of FAMILY PLANNING to make it more difficult to limit family size.
TAX on CONTRACEPTION medicine in order to reduce the demand.
OTHER POLICIES:
REDUCTION of STATE PENSIONS in order to encourage people to have children to support them in old age.
RAISE AWARENESS by using campaigns/advertising to encourage families to have more children.
ECONOMIC GROWTH refers to INCREASES in the LEVEL OF REAL GDP, as a result of INCREASES in the QUANTITY and QUALITY of an economy's FACTORS OF PRODUCTION.
Population growth resulting from net immigration/natural increase (rise in birth rate/fall in death rate) may INCREASE IN THE SIZE OF THE LABOUR FORCE, increasing productive potential/ability to produce products will rise.
The QUALITY OF THE LABOUR FORCE MAY INCREASE if the high population growth is the result of the immigration of skilled workers/more young people who have received better education than their elders, as this will increase productivity, increasing productive potential/ability to produce products will rise.
A growing population will ineviatably lead to INCREASES IN DOMESTIC DEMAND which will encourage firms to increase their output. This may also ATTRACT MNCs to set up in the country.
A higher population may make better use of resources and allow firms to take advantage of ECONOMIES OF SCALE.
ECONOMIC GROWTH refers to INCREASES in the LEVEL OF REAL GDP, as a result of INCREASES in the QUANTITY and QUALITY of an economy's FACTORS OF PRODUCTION.
A higher population may increase economic growth in terms of output but IF POPULATION GROWTH > GDP GROWTH then GDP PER HEAD FALLS.
A higher population may PUT PRESSURE ON RESOURCES and there may be less capital/land per worker, reducing productivity and resources may be diverted from increasing the productive capacity to coping with more dependents.
If the pop. growth consists of a RISE in the ELDERLY LIVING LONGER rather than MORE BIRTHS then it WON'T CONTRIBUTE TO ANY GROWTH IN THE SR.
LIVING STANDARDS can be measured in terms of the dimensions used in the HDI, such as HEALTHCARE (LIFE EXPECTANCY), EDUCATION (YEARS OF SCHOOLING), and INCOME (GDP PER CAPITA)
If there is an increase in the labour force MORE OUTPUT (REAL GDP) implying GREATER INCOME GENERATION.
With a larger population, market size will increase which may enable firms to take greater advantage of ECONOMIES OF SCALE, which lowers the average prices and RAISES REAL INCOMES makes items more affordable.
A large population is more attractive to MNCs who will wish to set up in the country in order to satisfy the growing demand, CREATING JOBS and INCOMES. In addition they will CREATE INFRASTRUCTURE to ensure GREATER GROWTH.
A larger population will inevitably mean GREATER TAX REVENUES, which can be used to invest in MERIT GOODS, such as eductaion and healthcare
Net immigration of workers may bring in new skills, that help OPEN NEW INDUSTRIES, CREATE JOBS and INCOME.
LIVING STANDARDS can be measured in terms of the dimensions used in the HDI, such as HEALTHCARE (LIFE EXPECTANCY), EDUCATION (YEARS OF SCHOOLING), and INCOME (GDP PER CAPITA)
If the higher population is a result of longer life expectancy amongst the over 65s then this may imply no gains to GDP simple a HIGHER DEPENDENCY RATIO, making the average citizen poorer.
If the population growth is extensive it may put PRESSURE ON LIMITED RESOURCES such as housing , school places, doctor services, etc...
Additionally, if the population growth is too sharp then their may be EXTERNAL COSTS such as pollution, erosion, and congestion.
If the population increases more rapidly than output, then GDP per head will lower.
If Emigration of dependents (1) would REDUCE THE DEPENDENCY RATIO on the remaining working population.
REDUCES GOV'T SPENDING on BENEFITS/PENSIONS etc... which means government spending on other items can increase•
If the emigration reduces an overpopulated location then OUTPUT PER HEAD SHOULD RISE per head should rise due to more efficient use of resources•
REMITTANCES MAY RISE as those who emigrate may send money back to relatives so this may increase living standards•
EMIGRANTS RETURN WITH NEW SKILLS and this may raise the productivity of the labour force
(1) Net emigration of workers (1) may result in money (remittances) being set home (1) such remittances may increase the income of their families (1) allowing them to buy basic necessities (1). Net emigration may result in ideas being set home (1) workers may later return with better skills (1) raising the country’s output (1) increasing employment (1). Wages may be raised (1) to retain workers (1). If a country is overpopulated (1) net emigration may enable there to be better use of resources (1). Net emigration of older people (1) may reduce dependency (1) lower cost of pensions (1) lower healthcare costs (1). Net emigration of unemployed/low-paid workers may reduce the number living in poverty (1)
BRAIN DRAIN as skilled workers may emigrate this will REDUCE THE QUALITY OF THE LF, which LOWER PRODUCTIVITY.
LESS ATTRACTIVE TO MNCs who will be deterred by the LACK OF SKILLED WORKERS.
DEPENDENCY RATIO WILL RISE if mostly people of working age emigrate, this will leave less 15-64 year olds to take care of the 0-14 & 65+ population.
CREATES UNDERPOPULATION, as the fall in population would result in a less than optimal levels and thus a fall in output per head.
LESS TAX REVENUE collected as there are less workers, meaning there are less funds for MERIT GOODS such as education and healthcare.
......
LARGER LABOUR RESOURCES, if the immigrants are of working age this could increase the productivity of the economy increasing the supply-side capacity of the economy leading to economic growth.
WILLINGNESS TO TAKE JOBS LOCALS WON'T hence filling seasonal shortages and improving overall productivity whilst keeping costs and prices low for example farm-hands.
WILLINGNESS TO WORK FOR LOWER WAGES so production COSTS would FALL leading to LOWER PRICES.
JOB COMPETITION LEADS TO BETTER QUALITY WORKERS as Immigration leads to increased competition for jobs so all workers need to IMPROVE their SKILLSETS, and PRODUCTIVITY in order to find work.
IMMIGRANTS BRING CAPITAL to start their own business CREATING MORE JOBS.
IMMIGRANTS SPEND THEIR INCOMES which will increase domestic consumption increasing total aggregate demand and creating ECONOMIC GROWTH economic growth.
IMMIGRANTS THAT WORK WILL PAY DIRECT TAXES which will INCREASE TAX REVENUE enabling more government spending on MERIT GOODS.
IMMIGRANTS TAKE JOBS AWAY FROM LOCALS, which means domestic unemployment in that country rises.
SOCIAL UNREST / RACIAL DISHARMONY may occur when BETTER SKILLED & QUALIFIED immigrants take jobs from less qualified and lower skilled local workers.
DEPRESS DOMESTIC WAGE GROWTH as Immigrants may be more willing to take up jobs with lower pay while locals will not feel that such low pay is appropriate depressing wage growth. LINK LINK
[+] Average level of experience of work force rises.
[-] Average level of new industry skills likely falls.
[-] Demand for healthcare services rises.
[-] Demand for retirement services rises e.g homes
[-] Rise in the cost of pensions to the government, may result in higher taxes for working age people to supplement it. VID LINK
[-] If the over 65 rate is growing faster than the rate of those of working age, then the dependency ratio will rise.
[-] Less income tax generation will mean the country can not afford its welfare sytems.
• Raise the retirement age.
• Make workers save for retirement eg CPF
• Raise productivity of workers through training.
• Encourage immigration of young skilled workers.
