At the most basic level, the increase or decrease in population can be calculated by following the simple formula:
BIRTH RATE – DEATH RATE + IMMIGRATION = GROWTH RATE
Please note that the model does not take immigration into account, so we are looking at birth and death rates only. The birth or death rate is the total number of births or deaths per year. However, as you’ll see in the simulator, below, birth rates are normally expressed as number of births per woman (over her whole life) and death rates as a percentage of people who die in each age group.
AA. Lessons > The Demographic Transition > Step 1
At the most basic level, the increase or decrease in population can bePart I To get a sense of this continuum, start by running the simulator(this link should be in your personal folder for AP ES) to 2050 for all seven countries (click on Open Simulator, top right of screen Run button). Record their population growth rates at the end of the simulated period in the Data Table and number the countries by growth rate from highest (earliest in the demographic transition) to lowest (farthest along the transition). Then answer the following questions.
- How do you suppose living conditions differ between the country furthest along in the demographic transition compared to the country earliest in the transition? How would living conditions in these two countries affect both birth and death rates?
- Think of three social factors that contribute to lower birth rates in the countries farther along. How might these social conditions be encouraged to emerge in less developed countries?
- In general, how do the concepts of "early, middle, and late demographic transition" map to the concepts of "first, second, and third world countries"?
What factors influence human population growth trends most strongly, and how does population growth or decline impact the environment? Does urbanization threaten our quality of life or offer a pathway to better living conditions? What are the social implications of an aging world population? You will discover how demographers approach these questions through the study of human population dynamics.
Part II go to step 2 (left panel) Read section “The overall population growth rate is only one of the differences among countries in different stages of the transition. The age-based population structure is also greatly affected. Note that the average………………….”
Answer :
- How does the shape of the population pyramid differ from most developed to least developed country?
- Those in the population who are in the "prime of life" (roughly aged 20-60, depending on local conditions), support the populations younger and older than themselves. How might this impact the quality of life in countries with the various shapes of demographic pyramids?
BB. Lessons > Population MomentumStep 1
Read Step 1 …”In this lesson, we explore population momentum (the time lag between a change in birth/death rates and the slowing of population growth). In Step 1, we explore the effect of changing the age …….”
Answer 1 and 2 by running the simulator.
1. How and why does the shape change?
2. How does an increase or decrease in the average childbearing age group change the population? Why do "first world" countries tend to have older childbearing women than "third world" countries?

1Population Dynamics
Consider the following questions
- How does population growth or decline influence economic and social well-being?
- Does population growth enhance or diminish economic growth?
- What impact does population growth have on poverty?
- Do specific aspects of population growth, such as age structure or sex imbalance, have bigger impacts on economic development and environmental quality than other aspects?
- What are the social and economic implications of population redistribution, through, for example, rural to urban or international migration?

Slums are a large and entrenched sector of many cities in the developing world. Some, like Brazil's favelas and South Africa's townships, have become sightseeing attractions.”
