• • 1. Define the term life expectancy.

    2. Describe the global life expectancy trend by using Figure One below.

    3. Describe the global distribution of similar life expectancies using Figure Two.

Activity Two - Describe - HALE or DALY

Clearly looking at just life expectancy is too simplistic when we need to consider a regions health, can HALE do any better?

• • 1. What is HALE and DALY?

Activity Three - Describe - Infant Mortality and Maternal Health

As you are beginning to see it is important to look at a range of indicators to see if countries are making progress in regards to its populations health. We are now going to focus on children and the impact of maternal health.

• • 1. Define Infant Mortality

    2. Using Figure Four, describe the changes in infant mortality. Don't forget to include data.

    3. What is Maternal Mortality?

    4. Describe the global distribution of Maternal Mortality using Image Five.

Activity Four - Describe - Ratio of People per Doctor

While it is good to look at pure indicators which focus on death as a way to compare the health of regions it is also interesting to look at what is potentially causing the premature deaths.

• • 1. How is the ratio of number of people per doctor expressed?

    2. Using the first link in the 'Useful Resources' box, describe the global distribution of the number of people per doctor.

Activity Five- Describe - Access to Sanitation

Sanitation is a key component when it comes to investigating health. If people do not have access to good sanitation then there is generally a higher risk of poor hygiene and people are more likely to be exposed to cholera, typhoid and polio. Today there is still over two billion people who do not have access to safe sanitation.

• • 1. What is meant by the term sanitation?

    2. How can sanitation be measured?

    3. Using Figure Six, describe the share of population with improved sanitation facilities.
