Advantages And Disadvantages Of Population Pyramids

Population Pyramids and Demographic Transition Model Activity

In the beginning of the late 1700s the death rates declined due to the advancement of technology in agriculture and production, it also increased due to the advancements in health and sanitation. This change in death rate caused people to live through their adolescent year, thus increasing thus life expectancy and creating a new movement for population growth. This sudden change created a shift in understanding the link between birth and death rate. Over the past 300 years, population demographics have continued to evolve as a result of the relationship between birth and death rates within a country [].

These observations and documentations of this global phenomenon has produced

Each different stage is characterized by a specific relationship between birth rate, the number of annual births per year, and the death rate, the number of deaths per year. As these rates change in relation to each other they greatly affect a country’s total population. Within the DTM a country will progress over time from one stage to the next, as certain social and economic factors act upon the birth and death rates3.

The different DTM stages 3:

Stage 1 - High stationary: It’s applied to most of the world before the industrial revolution. Both birth and death rates are high, as a result the population size remains fairly constant.

Stage 2 - Early expanding: The introduction of modern medicine lowered the death rates, especially among children. The birth rates remain high, the result is rapid population growth.

Stage 3 - Late expanding: The birth rates gradually decrease, this is usually due to a result of improved economic condition.

Stage 4 - Low stationary: Both birth and death rates are both low, thus stabilizing the population. Countries in stage 4 have a stronger economy, higher levels of edcuation, better health care and a fertility rate of two children per

The German government will pay the family until each child will turn 18. The maternity leave spans are 14 weeks, six weeks prior to the birth and 8 weeks after the birth.
