Population growth is the increase in the number of people in a population. Global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2022. It is expected to keep growing, although predictions differ as to when and if this growth will plateau.
The United Nations estimates that the population will reach 8.5 billion in 2030, 9.7 billion in 2050, and 11.2 billion in 2100. Other demographers have made different projections, with some estimating that the population will peak at around 9.7 billion in the 2060s and then start to decline.
There are a number of factors that contribute to population growth, including fertility rates, mortality rates, and migration. Fertility rates are the average number of children that a woman has in her lifetime. Mortality rates are the average number of people who die per year per 1,000 people in the population. Migration is the movement of people from one place to another.
Population growth can have a number of impacts on the environment, the economy, and society. Environmental impacts include deforestation, pollution, and climate change. Economic impacts include increased demand for resources, such as food, water, and energy, and decreased per capita income. Social impacts include increased poverty, crime, and conflict.
There are a number of things that can be done to address the issue of population growth, including family planning, reproductive health, and population control. Family planning is the practice of controlling the number and spacing of children. Reproductive health is the state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity in all matters relating to the reproductive system and its functions and processes. Population control is the practice of limiting the number of births in a population.
Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable development can help to address the issue of population growth by promoting economic growth, reducing poverty, and improving education and health.
The environmental impact of population growth is a major concern. As the population grows, so does the demand for resources, such as food, water, and energy. This can lead to deforestation, pollution, and climate change.
The economic impact of population growth is also a major concern. As the population grows, so does the demand for jobs and housing. This can lead to increased poverty, crime, and conflict.
The social impact of population growth is also a major concern. As the population grows, so does the strain on social services, such as education and healthcare. This can lead to increased inequality and social unrest.
There are a number of things that can be done to address the issue of population growth. Family planning, reproductive health, and population control are all important tools that can help to reduce the rate of population growth. Sustainable development can also help to address the issue of population growth by promoting economic growth, reducing poverty, and improving education and health.
Population growth rate
What is population growth rate?
The population growth rate is the average annual percent change in a population. It is calculated by dividing the natural increase (births minus deaths) by the population size and multiplying by 100.What are the factors that affect population growth rate?
The factors that affect population growth rate include fertility rate, mortality rate, and migration rate.What are the consequences of high population growth rate?
The consequences of high population growth rate include environmental degradation, poverty, and social unrest.
Population momentum
What is population momentum?
Population momentum is the tendency for a population to continue growing even after the fertility rate has fallen below replacement level. This is because the population is still made up of a large number of people of reproductive age.What are the consequences of population momentum?
The consequences of population momentum include environmental degradation, poverty, and social unrest.
Population density
What is population density?
Population density is the number of people per unit area. It is calculated by dividing the population size by the land area.What are the factors that affect population density?
The factors that affect population density include climate, resources, and technology.What are the consequences of high population density?
The consequences of high population density include environmental degradation, poverty, and social unrest.
Age structure
What is age structure?
Age structure is the distribution of a population by age. It is usually represented by a population pyramid, which shows the number of people in each age group.What are the factors that affect age structure?
The factors that affect age structure include fertility rate, mortality rate, and migration rate.What are the consequences of an aging population?
The consequences of an aging population include a decrease in the workforce, an increase in the demand for healthcare, and a decrease in tax revenue.
Urbanization
What is urbanization?
Urbanization is the process of people moving from rural areas to urban areas.What are the factors that drive urbanization?
The factors that drive urbanization include economic opportunity, education, and infrastructure.What are the consequences of urbanization?
The consequences of urbanization include environmental degradation, poverty, and social unrest.
Migration
What is migration?
Migration is the movement of people from one place to another.What are the types of migration?
There are two main types of migration: internal migration and international migration. Internal migration is the movement of people within a country, while international migration is the movement of people between countries.What are the factors that drive migration?
The factors that drive migration include economic opportunity, education, and conflict.What are the consequences of migration?
The consequences of migration include environmental degradation, poverty, and social unrest.
Fertility

Question 1
The world’s population is expected to reach 8 billion by 2023. Which of the following is NOT a factor that is contributing to this growth?
(A) Increased life expectancy
(B) Decreased fertility rates
(C) Increased urbanization
(D) Increased migration
Answer
(B) Decreased fertility rates.
The world’s population is growing at a slower rate than it did in the past, due to a decline in fertility rates. However, other factors, such as increased life expectancy and urbanization, are still contributing to population growth.
Question 2
Which of the following is NOT a consequence of population growth?
(A) Increased demand for resources
(B) Increased pollution
(C) Increased greenhouse gas emissions
(D) Decreased poverty
Answer
(D) Decreased poverty.
Population growth can lead to increased demand for resources, increased pollution, and increased greenhouse gas emissions. However, it is not necessarily associated with decreased poverty. In fact, some studies have shown that population growth can actually lead to increased poverty, as it can strain resources and make it more difficult to provide basic services to everyone.
Question 3
Which of the following is NOT a strategy for reducing population growth?
(A) Family planning
(B) Reproductive health
(C) Population control
(D) Sustainable development
Answer
(D) Sustainable development.
Sustainable development is a long-term strategy for meeting the needs of the present without compromising the ability of future generations to meet their own needs. It is not a strategy for reducing population growth.
Question 4
Which of the following is NOT a way to improve reproductive health?
(A) Access to contraception
(B) Access to safe abortion
(C) Access to prenatal care
(D) Access to education
Answer
(B) Access to safe abortion.
Access to safe abortion is a way to improve reproductive health, but it is not a way to improve reproductive health services. Reproductive health services include a range of services, such as access to contraception, prenatal care, and postnatal care.
Question 5
Which of the following is NOT a goal of population control?
(A) To reduce the rate of population growth
(B) To improve the quality of life
(C) To achieve a stable population
(D) To eliminate poverty
Answer
(D) To eliminate poverty.
Population control is a strategy for reducing the rate of population growth. It is not a strategy for improving the quality of life, achieving a stable population, or eliminating poverty.
