A country has a birth rate of 25 per 1000 and a death rate of 8 per 1000. Is its population growing, shrinking, or stable? Calculate the natural growth rate.
How does improving the literacy rate, especially among women, help in controlling population growth?
Odd One Out: Birth Rate, Death Rate, Population Density, Growth Rate.
Scenario: Two countries, A and B, have the same population size and the same birth rate. However, Country A has a much higher death rate than Country B. Which country is experiencing a faster population growth? Explain.
China's One-Child Policy
To combat a massive population explosion, China implemented the "One-Child Policy" from 1979 to 2015. This policy strictly limited most urban couples to having only one child. While the policy was successful in dramatically reducing population growth and contributed to economic growth, it also had significant negative consequences. These included a skewed gender ratio due to a traditional preference for male heirs (leading to sex-selective abortion and female infanticide), a rapidly aging population with fewer young people to support them (the "4-2-1 problem" where one child has to support two parents and four grandparents), and human rights concerns. This case study is a powerful example of a large-scale government intervention to control population and illustrates both the potential effectiveness and the profound social and ethical challenges of such policies.
Assertion (A): Advances in medical science have contributed to the population explosion in many developing countries. Reason (R): The development of vaccines, antibiotics, and better sanitation has led to a sharp decline in the death rate.
(a) Both (A) and (R) are true and (R) is the correct explanation of (A). (b) Both (A) and (R) are true but (R) is not the correct explanation of (A). (c) (A) is true but (R) is false. (d) (A) is false but (R) is true.
Vasectomy is considered a simpler and safer surgical procedure than tubectomy, yet tubectomy is performed far more often than vasectomy in many countries, including India. Provide some possible socio-cultural reasons for this discrepancy.
