• The population shown is shrinking

Describe what is happening to the pre-reproductive age cohort

• The cohorts are increasing over time

• The males are more numerous than the females

• The cohorts are all approximately the same

• Each succussive cohort is smaller than the one preceeding it

What two things could explain the difference in male v. female for the 80+ cohorts in this population structure

• Women, on average, outlive men

• This suggests sex selective behavior favoring females

• This could be the result of deaths in war 60 years ago
