What is population growth? The total number of human beings living in a particular area is known as a population. The total number of Total children, young people, and old people is known as a population.

The difference between populations in particular areas in a particular duration is known as population growth. The result of your current minus last year is known as population growth.

There are various reasons which will help us to increase the population growth. There are many factors that help us to increase population growth.

In this article, I am going to discuss the population growth determination factor. Virar basically Three Types of the reasons for population growth. Now I am going to mention all the regions which are the causes of population growth.

## 1. Fertility Rate

due to the fertility rate, the population growth will be increased. The fertility rate is the main cause for population growth.

The fertility rate helps us to count the total population in a particular area. If the fertility rate is increased then the population will also increase.

Otherwise, if the fertility rate also decreased then the population of a particular area also decreased.

There are many types of fertility rates. today in this article we are going to discuss the three types of fertility rates. We're going to discuss all the fertility rate types one by one below.

### 1.1 Crude birth rate

So if you are thinking about the crude birth rate then the total number of the birth rate divided by the total population of a particular area is known as a crude birth rate.

If you divide the total number of birth rates by the total number of population in a particular area then you will get the crude birth rate.

After getting the result you will know the fertility rate which will be one of the most amazing and easiest things. This is also one of the popular methods to find out the fertility rate.

This method helps us to find out the rate of birth date in a particular area doing this simple type of mathematical function.

**1.2. Standardized birth rate**

we will only count the total number of the 48 Hour birth rate of a specific region. It means in the standardized birth rate we will count only the specific region.

If we equal the total number of specific groups or specific ethnicities or a specific age group composition of a particular region then what will be the result that is known as standardized birth rate.

In the standardized birth rate, you do not count the whole population. We will just count the specific give reasons specific is group is specific sex composition of a particular region.

### 1.3. General or Total Fertility Rate

If we count the total number of the repeat optic capable women's number of a particular area without the total population of women then it is known as age or total fertility rate or General fertility rate.

If we divide the total birth rate of children divided by the number of fertility age group women, then we will get the result of the total fertility rate.

In total 43 to rate we will not count the total number of females. We will only count the total number of females who have the capability of reproduction.

We will deduct the numbers of the females who don't have the capability of reproduction and who don't have the capacity of being pregnant.

Show the formula of the total fertility rate each number of Total birth/numbers of fertility is a group admin.

## 2. Mortality Rate

How many people are drying in a particular area for a year it's known as mortality. The mortality rate is also one of the biggest reasons for population growth.

The population can increase or decrease due to the mortality rate. If there is a high mortality rate the population will decrease otherwise if there is a lace mortality rate in the population it will increase.

Basically, there are four types of mortality rates. I am going to mention all the four types of mortality rates in Bullet style. Crude mortality rate infant mortality rate maternal mortality rate standardized mortality rate

#### 2.1 Crude Mortality Rate

the ratio of the total number of deaths and the total population in a particular area is known as crude mortality rate. If we divide the total number of dates in a year by the total population of the particular country then you will get the crude mortality rate.

You can simply understand the formula for acute mortality rate, each crude mortality rate divided by the total population of a particular country.

### 2.2 Infant mortality rate

the total number of dying children for your particular area divided by the total number of living children is known as the infant mortality rate.

you will get the result of the infant mortality rate after dividing the total number of children dying by the total number of children leaving. Every year there will be a particular number of the death rate of children and the particular number of living children

. And you have to divide those numbers using the formula the dying number of children for ear / the total number of living children per year. Then you will get the results of the infant mortality rate.

**2.3 Maternal mortality rate**

if we calculate the total number of the data rate of children who are dying during the pregnancy divided by the total number of the children who are leaving after pregnancy.

Then you will get the total maternal mortality rate. Every year there will be many death cases related to pregnancy due to various types of reasons.

You have to count all the number of deaths of children during the pregnancy time then you will find out the total number of the maternal mortality rate.

So this is related to pregnancy that's why every year you have to calculate the total pregnancy and total birth rate to get the maternal mortality rate.

So guys the formula of maternal mortality rate is the total number of dead children in pregnancy time / the total number of living children per year after pregnancy.

### 2.4 Standardized mortality rate

we have to think that if the population of a particular region would be the same age as the country population then what would be the death rate? That is known as the standardized mortality rate.

We will guess the standardized mortality rate using prediction. The prediction means the death rate of a particular age group in a particular area is equal to the population of our country.

if you predicted that the death rate of a particular region equals the total population of a particular country then you will get a standardized mortality rate.

## 3. Migration

Migration is the main cause for an increase and decreases in population every year. So the main reason for population growth is migration.

Migration plays a greater role in population growth because it will have to increase or decrease the population full stop if migration increases the population of the particular area will be decreased if the migration is decreased then the population of a particular area will be increased.

Due to various reasons, humans will migrate from one place to another. The main reason for migration is the facility. Due to the lack of the facility then people decide to migrate from one place to another place.

In the scenario of Nepal, the migration rate is very high. The people are migrating from rural areas to urban areas because of the facility. The government suite brings a useful and effective campaign to control migration. Otherwise, the migration will be increased. According to the report of the census of Nepal 2078, the migration rate is increasing dangerously.

And the rural area is becoming empty. The government developed the infrastructure to provide the basic needs and services for the people living in rural settlements.

Migration will especially play a major role in the fertility rate and mortality rate for the population growth of a particular area. So in this article, we basically discussed the three types of reasons which are for population growth. Due to those reasons, population growth will happen.

The fertility rate, the mortality rate, and migration play a major role in population growth. If we discuss three things then you will find out the major problems for population growth. There could be various types of reasons for the population growth.

If you have any type of idea about population growth then you can give me suggestions in the comment box. All are very thankful and glad if you give me suggestions in the comment box. I will create more content related to these topics in the future.
