Question 1MediumLevel 85
If population was fifty lakh last decade and is now sixty lakh, what is the approximate growth percentage?
Correct answer: B
Increase is ten lakh, which is twenty percent of fifty lakh. Exam tip: use ( \text{Growth Percentage} = \frac{\text{Increase}}{\text{Previous Population}} \times 100 ).
If job opportunities increase in a city, which component of population growth may become more active?
Correct answer: B
More job opportunities attract people from other places to move into the city. Therefore, immigration becomes the active component contributing to population growth. Emigration means people leave the city, so it may reduce its population. Exam tip: link employment, education, and better facilities with immigration.
If birth rate is falling but death rate is falling faster, why can population growth continue initially?
Correct answer: A
Natural increase occurs when the number of births remains greater than the number of deaths. Even if the birth rate falls, population can still grow when the death rate falls faster and the birth rate remains above the death rate. In option B, growth would be zero, while in option C, population would decline. Exam tip: check the gap between birth rate and death rate, not only whether each rate is rising or falling.
