Human Population Growth

Key Questions

  • What factors affect human population growth?

    Answer:

    Population depends on the rate of growth , as well as external factors.

    Explanation:

    Population is influenced by factors like birth rate & death rate .

    1. Birth rate (Natality)- This refers to the number of newborns in a region at a given time.

    2. Death rate (Mortality) - This refers to the number of deaths in a region at a given time.

    Depending on whether birth rate/ death rate is more, the following trends are observed in a population:

    1. Steady population - This is when the birth rate is equal to the death rate. There is neither increase/decrease in the population.

    2. Declining population - This is when death rate is more than the birth rate.

    3. Growing population - This is when birth rate is more than the death rate.

    Another factor which influences population growth is competition .
