Environmental Science Activity: Constructing an Age Structure Diagram
Environmental Science Activity: Constructing an Age Structure Diagram
On the activity sheet is an age structure diagram template on which bars can be drawn to represent the population for each age group and sex. Data for constructing the diagram will come from Census Year 2000 data for the American Indian and Alaska Native group. Because emigration and immigration are not major factors influencing the population numbers for this group, one can see the future of the group’s population without substantial migration influences.
Use Table 2 to gather data for the number of males in each age group for the American Indian and Alaska Native. Be sure you use the column specified for that group:
Use Table 3 to gather data for the number of females in each age group for the American Indian and Alaskan Native. Be sure you use the column specified for that group:
Using the datasheets draw bars on the age structure diagram template to represent the populations for each age group of males and females. Three bars have already been drawn to demonstrate how it is to be done. The task can be done with a pencil and straight edge. Be sure to add color to the bars for added clarity and appeal.
Once finished with constructing the diagram, answer the questions on the activity sheet
Environmental Science: Age Structure Activity Sheet
1. Take a look at the shape of the diagram you have constructed. Would you say the diagram reveals a rapidly growing population, a numerically stable population, or a population facing negative growth? Explain how you made your decision.
2. Using the three age structure diagram examples from Mexico, Japan, and Iceland that you observed in the lecture portion of this activity, which one of these 3 countries is most comparable to the age structure diagram you constructed for the American Indian and Alaska
