Discuss the role of any two factors influencing population change.

The population can be defined as the number of people living in a particular area. It includes all the people living in the area, infants, children, and adults. The Population of a particular area is calculated by the government in the form of a periodic census. This census is conducted by the government. In the case of India, the census is estimated or surveyed once every 10 years. Currently, the world population stands at 8 billion people with India and China being the significant contributors to the population total. The average growth rate of the world population is 1.1 percent. The increase in world population between the years 1990 and 2010 is around 30 percent. The growth of the population depends on various factors like fertility rate, birth rate, mortality rate, migration, and many other vital factors. The change in population doesn’t only depend on the increase in population but also the decrease in population.

Major Components of Population Growth

Birth Ratio

This is one of the most important factors to be considered when we check the change in population. The Birth rate is the number of new children born into a particular area in a given period of time. The birth rate can be defined as the ratio between live births to 1000 people. Though the increasing birth rate is good it does not guarantee an increase in the net population. The rate of death in a given area is also very important when we consider the increase in population. The net birth rate or the net increase in the birth rate is equal to the difference in the birth ratio and death ratio. For there to be an increase in the birth rate the net Birth rate should be positive.

Over the years there has been a drastic decrease in the death rate. Many factors affecting the decrease in death rate are the increased per capita income, better availability of health cares system, and more literacy among people about healthcare. The advancement in technology has also led to an increase in healthcare facilities which in turn helps increase the life expectancy of the people.

Migration

Migration is the phenomenon in which one organism moves from its natural habitat to some other place. Migration is a phenomenon associated not only with humans but also birds and animals. Though in this case, it refers to the movement of people from one location to another. This movement might be due to a number of reasons like moving for better opportunities, or the intention of settling in a particular area temporarily or permanently. The migration of people from one place to another might be internal or external. Internal migration is the case when a person moves from one place to another within the same country in this case there is no change in the net population of the country. External population referees when a person moves from one country to another thus affecting the net population of both places.

There is an increase in the population of the country when the birth rate is more than the death rate and when the number of people moving in the country exceeds the number of people who want to move out of the country. Thus Birth rate and Migration are one of the most important factors affecting change in population.

Why discuss the role of any two factors influencing population change?

Understanding the factors affecting demographic change is important for a variety of reasons, including social, economic, and policy. There are two main reasons why it is important to discuss the role of these factors.

1. Policy design and resource allocation: Demographic change has important consequences for various segments of society, including health, education, housing, infrastructure, and social welfare By examining the factors affecting demographic change, policymakers be able to make informed decisions and allocate resources effectively. For example, if a region is experiencing rapid population growth, policymakers can anticipate and plan accordingly for increased demand for health care, schools, and housing Understanding the drivers of demographic change, allowing for early intervention planning and resource allocation to meet changing population needs.
2. Socio-economic impact: Demographic changes can have significant socio-economic impacts. It affects the labor market, labor force, economic growth, dependent population density, and the social welfare system. For example, low fertility rates can lead to labor shortages, problems with social security systems and demographic challenges, such as an ageing population On the other hand, population movements the rapid rise may present opportunities for economic growth but also challenges in providing adequate services and employment s Gain insight into the topic and develop strategies to address the challenges involved or they will take advantage of potential opportunities

Q 2. List the factors which affect Population Change.

Answer-

The change in population doesn’t only depend on the increase in population but also the decrease in population. The growth of the population depends on various factors like fertility rate, birth rate, mortality rate, migration, and many other vital factors.

Q 3. What is Death Rate and What is the reason for decreasing death rate?

Answer-

The ratio of the number of people who died for every 1000 people is known as the death rate. Many factors affecting the decrease in death rate are the increased per capita income, better availability of health cares system, and more literacy among people about healthcare.

Q 4. What is the Net Birth Rate?

Answer-

The net birth rate or the net increase in the birth rate is equal to the difference in the birth ratio and death ratio. For there to be an increase in the birth rate the net Birth rate should be positive.

Q 5. What are the classifications in Migration?

Answer-

The migration of people from one place to another might be internal or external. Internal migration is the case when a person moves from one place to another within the same country in this case there is no change in the net population of the country. External population referees when a person moves from one country to another thus affecting the net population of both places.
