Population Age Structure Diagram Analysis Directions: After completing the age structure diagram for one country, answer the following questions below using complete sentences. 1) What country did you draw? 2) Which type of age structure did that country turn out to be (pyramid, rectangular, inverted)? How can you tell? 3) Is this country classified as developed or developing? 4) How is the GDP (gross domestic product) of this country? 5) What type of industries can be found in this country? 6) Describe the birth rate trends of this country. 7) Describe the death rate trends of this country. 8) Is this country overexploiting its natural resources? Explain. 9) What are 3 environmental issues that are created from overpopulation? 10) What do you think is the best way to limit population growth? Explain. 11) Why are age structure diagrams used by scientists? Three (3) Age Structure Diagrams 1. Expanding/growing population (Pyramid)-Pyramid shape, has more children than any other age group. Lots of reproductive women. Low GDPs. High Birth rates, High death rates. Lack of medicinal care. Agriculture based economies. Common of developing countries- Ex: Nigeria or Bolivia 2. Stable populations (Rectangular)-Number of children is roughly the same as the number of reproductive adults. Births can equal deaths throughout the ages. High GDPs. Industrial based economies. Educated women = lower birth rates. Common of developed countries- Ex: European countries, U.S.A. 3. Declining population (Inverted)-Pre-reproductive group is smaller. Not enough reproductive woman having babies to replace the older generation. High GDPs. Industrial based economies. Common in developed, progressive countries- Ex: Japan, Germany (Russia, Bulgaria qualify due to emigration)
