Arrange the following as per the stages of the demographic transition model:

(A) Population growth is slow due to high birth and high death rate.
(B) Fertility remains high, but mortality declines at a faster pace.
(C) Fertility declines at a faster pace, but mortality declines gradually.
(D) Population growth is slow due to low birth and low death rate.

Choose the correct answer from the options given below:

The correct answer is (A), (B), (C), (D).

The Demographic Transition Model (DTM) describes how a country's population changes over time as it develops economically and socially. The model typically consists of four main stages, which correspond to the sequence of statements given in the question:

Stage 1: High Stationary Stage (Statement A)
In this initial stage, both birth rates and death rates are high and fluctuate rapidly. As a result, population growth is extremely slow and stable. This corresponds to statement (A): "Population growth is slow due to high birth and high death rate."

Stage 2: Early Expanding Stage (Statement B)
With improvements in healthcare, sanitation, and food supply, the mortality (death) rate declines rapidly. However, fertility (birth rate) remains high because social norms take longer to change. This leads to rapid population growth. This corresponds to statement (B): "Fertility remains high, but mortality declines at a faster pace."

Stage 3: Late Expanding Stage (Statement C)
During this stage, birth rates begin to fall rapidly due to access to contraception, urbanization, and changing social structures (e.g., women's education). The death rate continues to fall, but at a much slower, gradual pace. The rate of population growth begins to slow down. This corresponds to statement (C): "Fertility declines at a faster pace, but mortality declines gradually."

Stage 4: Low Stationary Stage (Statement D)
In this stage, both birth rates and death rates are low, leading to a stable or slow-growing population once again. This corresponds to statement (D): "Population growth is slow due to low birth and low death rate."

Therefore, the chronological sequence of the stages is (A), (B), (C), (D).
