Population: Demographic Transition Models
Part I: Sweden & Mexico
In order to complete the following items for part I, you must refer to the blog for figures and models that will assist you.
Using the data provided, observe the two Demographic Transition Models for Sweden and Mexico.
Carefully examine the 2 graphs in order to help answer the following questions. Notice
that there is a significant difference in the dates along the horizontal axes. You must
print both DTMs and turn in with answers to the following questions.
1)a)In both Sweden and Mexico which seems to decline first – birth or death rates? (This is the same for all countries, just observe which one declines first on the DTM in Stage 2)
b)Suggest some reasons for this.
c)Did the death rate decline in Sweden or Mexico first? Why do you believe this was the case?
2)What happened to the rate of natural increase as the death rates began to drop?
3)a) When did the birth rates seem to start going down on a fairly regular basis in each
country?
b)What effect has the declining birth rates had on the rate of natural increase?
c)Why has Mexico’s birth rate decline started much more recently than Sweden’s? (Consider when the two countries went through Stage 3)
d)Once Mexico’s birth rate did start to decline, it was a very slow decline, even into thelate 1900s. Why?
4)a)Using the DTMs provided, draw lines indicating where you believe the various
stages of the demographic transition model start and end.
b)Have both countries gone through all 4 stages? Explain.
5)What do you notice about the length of time (number of years) between the start of the
2nd stage and the end of the 3rd stage for Sweden? Estimate how long this period will be
for Mexico. Explain the difference.
6)a)What is similar about Stage 1 and Stage 4 of the Demographic Transition Model?
b)What is very different about these two stages?
c)What conclusion can you draw about low rates of natural increase?
Part II: Identifying the Stages of Demographic Transition
