demographics online lab write-up

Africa vs the world
UK vs the world simulation pic

Post the two screen shots: one should have the world simulation compared with a lower fertility rate country or region; one should have the world simulation compared with a higher fertility rate country or region.





1. What was your high fertility rate country and what was its fertility rate?




africa




5.90 children




2. What was your low fertility rate country and what was its fertility rate?





the UK





1.80 children










3. The initial demographic "shape" of your high fertility rate country should have been a pyramid, with high population in young age groups. Explain why high fertility rate results in a high percentage of young people in the population. How does this affect future population growth?




well,if there were five babies born per mother,I'm pretty sure that the percentage of young people in the population is going to increase rapidly...






4. Your low fertility rate country might have had a more oval-shaped curve with high population in middle age groups. This is especially exaggerated if the fertility rate is below 2.00. Explain why low fertility rate leads to lots of middle-aged people.





because of postreproduction,mortality and infant mortality rates.postreproduction means that there are more older woemen leaving the reproductive years than woemen entering them,so basically, less babies,more deaths.low fertility rate country.






5. Imagine a situation with lots of middle-aged and older people in the population and write ten quick "brain-storm" descriptors for you think it would be like




sighns saying no skateboarding




mid life crisis;fancy sports cars




insanity about yards being perfect




desperate housewives




pampered pets




uptight




lots of phone calls to the police




old people on bikes trying to stay in shape




perfect houses with polish cleaning ladies




homeowners association




***I actually asked someone who experienced this firsthand***




5 b:Then do the same for a situation with lots of children in the population.




kids almost everywhere




overwhelmed police force




pregnant teenagers




younger parents




swamped abortion clinics




overly strict parents




parents who don't care




shouting and loud noises coming from houses




full playgrounds




school overpopulation
