|
|
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: -This occurs where birth and death rates are both low, leading to a total population stability. Death rates are low for a number of reasons, primarily lower rates of diseases and higher production of food.
Detailed explanation-2: -In Stage 4, birth and death rates are both low, stabilizing the population. These countries tend to have stronger economies, higher levels of education, better healthcare, a higher proportion of working women, and a fertility rate hovering around two children per woman. Most developed countries are in Stage 4.
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: -the fourth phase of population cycle which is characterized by stagnation or an actual decline in the total population of a country due to an excess of deaths over births.
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.
