U3: 3.6

Question 1

Define the term Age Cohort

Answer 1

Groups of similarily aged individuals.

Question 2

Identify the three key age cohorts used for interpreting age structure diagrams.

Answer 2

0-14 (pre-reproductive), 15-44 (reproductive age), 45+ (post-reproductive)

Question 3

Explain what an age-structure diagram with a larger portion of individuals in the pre-reproductive age cohort than any other cohort can tell you about the population.

Answer 3

Can tell you that the population is expanding rapidly. because there is current rapid growth and there will be future growth. (Extreme Pyramid shape)

Question 4

Explain what an age structure diagram with a slightly larger pre-reproductive age cohort than reproductive age cohort can tell you about the population.

Answer 4

Tells you that the population is expanding slowly because there is current stable growth and there will be future growth. (Pyramid shape)

Question 5

Explain what an age structure diagram with roughly equal pre-reproductive and reproductive age cohorts can tell you about the population.

Answer 5

Tells you that it is a stable population, because there is a slight growth rate/stable population. (House/Empire state building shape)

Question 6

Explain what an age structure diagram with a greater proportion of individuals in reproductive and post-reproductive age cohorts than pre-reproductive age cohorts can tell you about the population.

Answer 6

Tells you that it is a declining population. because there are less pre-reproductive (young people) to promote population growth. (Ice cream cone shape)
