    Distinguish between population growth and population change.

    Open in App Solution Population Growth

    Population change can be understood in two different ways – one is in terms of percentage change per year and the other is in terms of absolute numbers.

    During a specific time period, in a specific territory or country, the change in the number of inhabitants is known as the growth of population.

    Population Change

    Population change is nothing but the change in composition, distribution, and the change in numbers due to three processes such as migration, births, and deaths.

    Birth Rate

    A number of live births per thousand persons in a year is known as the birth rate.

    In India, birth rates have always been higher than death rates, hence it is one of the major components of the population growth rate in India.

    Migration

    An important determinant of population change is migration.

    Migration not only changes the size of the population but also changes the composition of the population in rural and urban areas.

    The movement of people across different territories and regions is known as Migration.

    Migration can take place between different countries (international) or within the country (internal).

    The size of the population is not changed by internal migration.

    Due to unemployment and poverty in rural areas and the plenty of employment opportunities and better living conditions in cities drives the migration of the population from rural areas to urban areas.

    Death Rate

    The definition of death rate is the number of deaths per thousand people in a year.

    The rapid decline in the death rate has been one of the main causes behind the growth rate of the population in India.

    Hint: Population growth and Population change made an important change in the country. Through these changes, the other factors like the economy and society change from time to time and place to place.Complete answer:

    Population Growth Population Change

    Population growth refers to the change in the number of inhabitants of a country and territory during a specific period of time like the last ten years, last 15 years and so on. Population change refers to the change in the number of people during a specific period of time.

    It can be expressed in terms of absolute numbers and in terms of the percentage change in a year It can be expressed in the number of individuals.

    Population growth is when population increases. Population change can be increase and decrease

    Population growth can be determined by the difference between birth rate and death rate with migration per year Population change can be determined by the difference between the size of the population from the beginning to the end of a certain time period.

    Population growth does not alter the population composition. Can alter the population composition.

    Population change in terms of birth rate changes as it is the number of lives per thousand persons in a year. In India, it is a major component of growth as the birth rate has always been higher than death rates.

    The death rate is the number of deaths per thousand persons in a year and there is a growth of the Indian population because the death rate is declining.

    Another major component of population growth is migration, It is a movement of people from one place to another, which means across regions and territories. It can be internally (within country) or externally (between the countries).

    Note: Population in India in 2020 is estimated to approximately 1.38 billion people. India is the second-largest country in terms of population after China.

    The main difference between population growth and population change is that the population growth is the increase in population due to natural growth and migration whereas the population change is the change in the population composition. Furthermore, population growth has no influence on the population composition while population change alters the composition of the population.

    Population growth and population change are two parameters of ecology used to describe a particular population of living organisms.

    What is Population Growth

    Population growth is the increase in the number of individuals in a population. The two factors involved in the increase in the number of individuals in a population are birth rate and migration into the population. Meanwhile, the death rate and the migration out of the population decrease the number of individuals in a population. Therefore, the formula for the population growth is as follows:

    Population Growth = (birth rate + immigration) – (death rate + emigration)

    Figure 1: Population Growth in Africa, 1950 – 2050

    Population growth is an exponential process; hence, the population increases by a constant amount over a period of time. It is affected by the number of individuals already present in the population. Other factors such as fertility and rates of motility also affect the growth of the population. This means population growth cannot be considered as a linear process involved in the constant doubling of individuals. Moreover, population growth is one of the main problems behind many ecological problems since it increases the demand for resources.

    What is Population Change

    Population change is the difference in the size of the population from the beginning to the end of a certain period of time. Some populations decrease their size while others such as the human population increase in size. Hence, populations are not stable. The change in the population also changes the composition of the population defined by the birth and the death rates, sex ratios, life expectancy as well as the migration rates.

    Similarities Between Population Growth and Population Change

    Population growth and population change are two parameters used to describe the changes which occur in a particular population.

    Both can interpret the increase in the number of population.

    Difference Between Population Growth and Population Change

    Definition

    Population growth refers to the increase in the number of individuals in a population while population change refers to the change in the number of people during a specific time period. This explains the basic difference between population growth and population change.

    Determination

    Another difference between population growth and population change is in their determination. Population growth can be determined by the difference between birth rate and death rate plus migration per year while population change is determined by the difference between the sizes of the population from the beginning to the end of a certain time period.

    Expression

    Also, the population growth is expressed in percentage while population change is expressed in the number of individuals.

    Significance

    Furthermore, population growth is the increase in the population while population change can be either an increase or decrease.

    Population Composition

    One other difference between population growth and population change is that the population growth does not alter the population composition while population change can alter the population composition.

    Examples

    Population growth is 1.1% per year while the human population change is 0.804 billion from 1991 to 2001.

    Conclusion

    Population growth is the increase in the number of population while population change is the change in the number of individuals in the population, which can be either increase or decrease. The main difference between population growth and population change is the type of change in the population.
