Example response:
In the lecture, the professor speaks about populations that have zero growth; in other words, they have no change in their population.
She also talks about negative population growth, or populations that are shrinking. He cites low birth rates, caused by an imbalance of the sex-age structure, as a reason for these types of population change.
She also mentions migration, or movement of the citizens of one country to another country, as well as the death rate, which might rise dramatically in the case of an outbreak of a disease or in the event of a natural catastrophe or disaster.
The reading passage expounds on the sex-age structure, which crucially affects the demographic of men and women of child-bearing age.
But, it doesn’t discuss zero or negative population growth.
The reading passage also points out that governments need to monitor the age-sex structure because it can significantly impact upon social policies, like pensions and education.
