Living in the Environment 18th Edition by Tyler Miller,Scott Spoolman

تمرين 5

Prepare an age-structure diagram for your community. You will need to estimate how many people belong in each age category (see p. 131). To do this, interview a randomly drawn sample of the population to find out their ages and then divide your sample into age groups. (Be sure to interview equal numbers of males and females.) Then find out the total population of your community and apply the percentages for each age group from your sample to the whole population in order to make your estimates. Create your diagram and then use it to project future population trends. Write a report in which you discuss some economic, social, and environmental effects that might result from these trends.
