Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Name three official sources of data on the health of the population.

    Model answer

    Registered deaths with their recorded causes, hospital and general practice records, and national household surveys that ask people about their own health.

  2. 2

    What is a standardised mortality ratio?

    Model answer

    It is a measure comparing the deaths in a group with the deaths expected if that group had the national age pattern, where 100 represents the national average.

  3. 3

    How is the infant mortality rate calculated?

    Model answer

    It is the number of deaths of children under one year of age for every thousand live births in the same period.

  4. 4

    Why is infant mortality treated as a key indicator of a society's health?

    Model answer

    It is sensitive to nutrition, housing, maternal health and the quality of health services, so it summarises the living conditions of a whole population.

  5. 5

    What does the census ask about health?

    Model answer

    It asks people to rate their own general health and to say whether they have a long-term illness or condition that limits their daily activities.

  6. 6

    Which national survey collects data on health in Wales?

    Model answer

    The National Survey for Wales, which asks a random sample of adults about their health, lifestyle and use of services.
