Explain how infant mortality can be used to measure the health status of a population.   (4 marks)

Show Answers Only
  • Infant mortality reflects a population’s overall wellbeing and survival prospects. This occurs because it measures deaths before age one, which indicates underlying health conditions.
  • Low infant death rates demonstrate effective healthcare access and quality medical services. This shows that preventative measures like immunisation programs and maternal support are working successfully.
  • For instance, when Australian infant mortality declined from 2010 to 2020, this revealed improvements in prenatal screening and neonatal care. As a result, more infants survived their vulnerable first year.
  • Infant mortality data enables health authorities to identify at-risk communities. This allows targeted interventions where mortality rates remain elevated.

Australia's Health 2024 report states that 

"Over the last century there have been substantial decreases in child and infant mortality rates, contributing to increases in overall life expectancy. For example, death rates for children under 5 declined by 97% between 1907 and 2022."

Outline how the decrease in infant mortality rates in Australia over the past century has contributed to increased life expectancy.   (2 marks)

Show Answers Only
  • The significant decrease in infant mortality rates in Australia has contributed to increased life expectancy by reducing deaths in the early years of life.
  • As more children survive past their first year, the average life expectancy of the population increases because fewer lives are being cut short in infancy.

When examining infant mortality as a health indicator, which of the following statements is most accurate?

  1. It measures deaths of all children under 18 years per 1,000 population.
  2. It measures deaths among children aged under one year per 1,000 live births.
  3. It only accounts for deaths occurring during birth, not those occurring after hospital discharge.
  4. It is typically calculated as a percentage of all deaths in a country.

Show Worked Solution
  • B is correct. Infant mortality measures deaths among children aged under one year per 1,000 live births.

Other options:

  • Option A is incorrect as it refers to all children under 18, not just infants.
  • Option C is incorrect as infant mortality includes all deaths under 1 year, not just those during birth.
  • Option D is incorrect as infant mortality is calculated per 1,000 live births, not as a percentage of all deaths.

  • A is correct: Australia shows decreasing infant mortality rates and increasing life expectancy trends.

Other Options:

  • B is incorrect: Life expectancy continues to increase in Australia.
  • C is incorrect: Infant mortality is decreasing, not increasing.
  • D is incorrect: Infant mortality is decreasing, not stable.
