can you tell?

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)
