Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In the first stage of the demographic transition
A
birth rates stay high but death rates start decreasing increasing population size
B
birth rates and death rates are both low so population starts decreasing
C
birth rates and death rates are high meaning high stable population
D
birth rates and death rates are decreasing so population growth starts slowing down
Explanation: 

Detailed explanation-1: -Stage 1-High birth and death rates lead to slow population growth. Stage 2-The death rate falls, but the birth rate remains high, leading to faster population growth. Stage 3-The birth rate starts to fall, so population growth starts to slow.

Detailed explanation-2: -Stage 1 of the Demographic Transition Model (DTM) is characterized by a low population growth rate due to a high birth rate (number of annual births per one thousand people) and a high death rate (number of annual deaths per one thousand people).

Detailed explanation-3: -Demographic cycle First stage (High stationary): This stage is characterized by a high birth rate and high death rate which cancel each other and the population remains stationary.

Detailed explanation-4: -In the first stage, both the birth and death rates are high. The high birth rate is due to common early marriages, illiteracy, and the absence of knowledge of different methods of family planning. Death rates are high because there is no proper diet and not enough medical or sanitation facilities.

Detailed explanation-5: -During the first phase, the population growth rate rises as the death rate declines while the birth rate remains high. In the second phase, the growth rate declines (but remains positive) due to a decline in the birth rate.
