Answer 10

infant mortality rate
- reflect the annual number of deaths of infants under 1 year of age per 1000 live births
* an indicator of a country’s health care

Question 11

high in peripheral low in core countries

Question 12

Answer 12

movement and migration of people

movement - international, or just within a city for example
