Correct option is A
Ans: (a)
Explains the changes in birth and death rates
Sol. The
Demographic Transition Theory explains the changes in
birth rates and
death rates as a country develops from a pre-industrial to an industrialized economy. It suggests that as societies progress, they experience a transition from high birth and death rates to low birth and death rates. This theory is divided into four (sometimes five) stages:
·
Stage 1: High birth rates and high death rates.
·
Stage 2: High birth rates and declining death rates (due to improvements in healthcare and sanitation).
·
Stage 3: Declining birth rates and low death rates.
·
Stage 4: Low birth rates and low death rates, leading to a stable or slowly growing population.
Explanation of each option:
·
(a) Explains the changes in birth and death rates: Correct answer. The Demographic Transition Theory focuses on how birth and death rates change over time as a country develops economically and socially.
·
(b) Study migration patterns: Migration patterns are an important aspect of population studies, but they are not the focus of the Demographic Transition Theory.
·
(c) Analyze the impact of urbanization: While urbanization can influence birth and death rates, the Demographic Transition Theory primarily concerns the evolution of these rates, not urbanization itself.
·
(d) Predict future population growth: While the Demographic Transition Theory provides insights into population trends, it does not specifically predict future growth. It primarily explains historical patterns of population change.
