|
|
birth rates stay high but death rates start decreasing increasing population size
|
|
|
birth rates and death rates are both low so population starts decreasing
|
|
|
birth rates and death rates are high meaning high stable population
|
|
|
birth rates and death rates are decreasing so population growth starts slowing down
|
Detailed explanation-1: -The third stage of demographic transition is characterised with low growth rate of population due to decline in both birth as well as the death rate.
Detailed explanation-2: -In Stage 3 of the Demographic Transition Model (DTM), death rates are low and birth rates decrease, usually as a result of improved economic conditions, an increase in women’s status and education, and access to contraception.
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: -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.
Detailed explanation-5: -Stage 1: High birth rates and death rates: This stage is characterised by high birth rates, high death rates and little population growth. Total population numbers are low and the high birth rate is balanced by the high death rate.
