Lesson Details

Key learning points

Life expectancy is the measure of how long a person is expected to live.
Life expectancy varies worldwide and involves many factors.
The average life expectancy in the UK is around 79 years for males and 83 years for females.
Life expectancy can be researched using secondary sources of information.
Life expectancy can be plotted on a line graph to show changes over time.

Common misconception

Pupils may think that life expectancy is a prediction for individuals or a guarantee.

Using the lesson resources to support, explain that life expectancy is a measurement we can make using data that we have about human lifespans. We cannot use it to predict how long an individual or group’s life will be.
