2. How Can the Data Be Used?
4 The students' work is organised around several central questions. This list is not exhaustive and students are expected to generate at least one question of their own (and to try to answer it).

Do people living in different countries have similar life expectancies?
Do men and women have similar life expectancies?
Are birth rates related to death rates?
How quickly are populations growing?
