## What is the definition of population growth?

Population growth is the growing population as a result of reproduction.

## What is the rate of population growth?

A population growth percentage is a rate at which a population increases each year or over the time period being studied.

## What kind of growth sees the population?

While population growth tends to be exponential, once in a while all populations will reach a tipping level where they are unable to sustain their growth rate because of many factors, such as food supply and health.

## Key points regarding population

• A population refers to a group of individuals of the same species or society that live in the same habitation or environment.
• The population can be defined as a group of individuals or a collection of people.
• Fluctuations in the birth rate and death rate can lead to a population changing or increasing and declining.
• An increase in Population simply refers to an increase in the size of the population.
• Demographic growth refers to the alteration/increase of a population that is greater than time.
• Population growth is defined as an alteration in the number and species of individuals within a population. It can be measured using "per-unit time" to measure.
• Population growth can both be expressed in relative and absolute terms.
• ## What Major Factors Affect Population Growth?

Population growth relies on four basic factors: birth, death, immigration, and migration.
Population growth rate= (birth rate + immigration) - (death rate + emigration)

### 1. Birth Rate

• The population will logically increase if there are more births than there are deaths or if the rate of death is lower or higher relative to the birthrate.
• The formula used to calculate the crude infant mortality rate is
• Crude Death Rate (CBR), = Number Of Births Within a Year/Total Mid-Year Population x 1000

### 2. Mortality Rate/Death rate

• The death rate or mortality rate is one of the most important factors that influence the growth of the population.
• As the population increases, so does the death rate. The accessibility and affordability for quality health care, as well daily life practices, are the main factors that influence the mortality rate.
• The formula used to calculate the Crude Death Ratio is
• Crude Rate of Death (CDR), = ( Numbers of deaths in a year/Total middle-year population)x 1,000

### 3. Immigration and Emigration

• Migration is when people move from one place/country into another.
• Emigration and immigration are two different types of migration.
• Immigration (moving to The place/country): This is the movement and integration of people from other parts of the world.
• Emigration ( Leaving from a Place/Country) is the movement and exclusion of individuals from a population.
• The size of the country's population is affected by Immigration and Emigration.
• Emigration is a result of many factors.
• A nation's population decreases slowly after an individual emigrates.
• It is called "immigration" when someone travels to another country.
• There are two sides to migration.
• There are many factors that attract people to a particular country/place. One example of a pull factor is better job opportunities, better social security, better medical facilities, and improved education systems.
• People often leave their country/place of residence due to push factors. You can think of several factors that could cause people to leave the country or place: lack of social harmony and peace; increased conflict; poor education systems; poor job opportunities; inadequate resources.

### A) Government Plans/Policies

• Plans and policies of the government have a major impact on population growth.
• Some people in the world, including administrators and legislators, agree that certain countries must have a limit on the country's birth rate.
• China's well-known one-child policy prohibited couples from having more kids than the set number. This dispute supports the idea that such a restriction would lead to less resource usage and reduce overpopulation.
• Furthermore, different governments and countries have developed different plans and policies in order to stop population growth.
• ### B) Biotic and intrinsic elements

The biotic and intrinsic factors are:
• Age of reproductive maturity
• Number of offspring that are produced by a reproductive event
• There are many reproductive events during a lifetime.
• These three factors can be combined to create fecundity.

### C) Environmental factors

• Environmental resistance factors
• ### D) Emancipation/liberation of women

• Increasing emancipation/liberation/freedom of women has increased their access to education, work, and other outdoor activities, ultimately leading to delayed childbearing.
• It also leads to fewer children being conceived per woman.
• ### E) Urbanization

• Urbanization is associated with higher birth rates, but lower deaths.
• People have greater access to and more use of urban facilities that can increase their birthrate. In turn, infant mortality and neonatal mortality decrease.
• However, urbanization may lead to a decrease in birth rates due to higher education and greater use of family planning.
• ### F) Agricultural changes

• Agricultural advances have increased the production of food.
• The death rate from famine has been decreased by the increased production of foods.
• People can also ensure that their children have enough food.
• ### G) Education

• Education is an important factor in population growth.
• An increase in education results in increased use of family-planning devices, better planning of resources, and lower birth rates.
• Education helps people to be aware of the basics of WASH (Water, Sanitation, and Hygiene), and thus prevents them from developing simple and preventable illnesses like cholera, typhoid, and others.

### 1. Biological Factors

• Mensuration, sex, and age
• ### 2. Physiological factors

• Sterility - A phase in a woman's reproductive pattern that is unviable or sterile.
• ### 3. Social factors

• Religion
• Caste system
• Racial groups
• Customs
• Family systems
• Education
• Status of women
• ### 4. Economic factors

• Urbanization
• Occupation
• Economic Conditions
• Planning for the family

### 1. Medication to prevent disease

• Development countries have benefited from the international collaboration and support of developed countries for importing drugs.
• Thus, the provision has helped to eradicate certain diseases such as smallpox, polio, and TB. to a substantial level.
• ### 2. Public Health Programs

• The WHO has provided assistance to developing countries in launching many public health programs, such as free immunization campaigns, environment preservation, and tobacco control programs.
• Similar arrangements have been made by the government regarding pollution control. In turn, respiratory diseases have seen a decrease in deaths.
• ### 3. Healthcare facilities

• Infected diseases can be combated by various medical and health care institutions.
• A meteoric phase of privatization and reduction in government hospitals has resulted in better medical facilities that have helped to reduce the death rate.
• ### 4. Education is on the rise

• The education on healthy lifestyles and eating well has helped to lower the rate of death.
• ### 5. Status of Women

• In most developing countries, literacy has led to women becoming empowered. Women now understand the importance and benefits of sanitation and hygiene. The infant mortality rate is also decreasing.
• ### 6. Food supply

• A rise in the food supply in the mainstream countries of developing countries, and imports of grain from developed countries. This has resulted in a reduction of deaths from famines.
• ### 7. Life Expectancy

• Economic development is the process of i.e. Economic development is the increase in per-capita incomes and improved health facilities. In developing countries, it has been able to increase the life expectancy rate of people compared with previous years. This consequently decreases the death rate.

### 1. Socio-political elements

• War can occur for many reasons, such as political disputes or arguments. As a result, it is the largest factor that impacts migration.
• Example: In Syria people moved from one country to the other in search of security and access to healthcare.
• ### 2. Economic factors

• Economic factors include the unemployment situation and brain drain as well as the decline phase of businesses.
• Furthermore, wages are higher, and there are better job options. The migration of skilled labor/intellectuals from developing areas/countries can be a result.
• These factors are also responsible for migration.
• ### 3. Ecological factors

• The Intergovernmental Panel on Climate Change reported that climate change would have an important impact on food security by mid-century.
• The possibility of rural to urban migration, or increased international emigration in areas that cannot sustain agriculture is possible.
• Water security is another factor that can cause severe food insecurity. Growing water insecurity in different regions of the globe can have an impact on international migration.
• Individuals who are suffering from adverse environmental conditions can choose to migrate to a better environment in another country.
