What is South Africa's life expectancy at birth?

• A. 55.3 years
• B. 75.2 years
• C. 68.4 years
• D. 62.8 years

Answer: (D)

Life expectancy at birth is the average number of years a newborn would live if current mortality rates stayed the same over time. In South Africa, this measure reflects the impact of major health challenges, notably the HIV/AIDS epidemic and the rollout of antiretroviral treatment, which have kept the national average in the low-to-mid 60s rather than climbing into the 70s. The figure around 62.8 years fits the recent pattern for the country, capturing improvements from ART but still lower than many high-income countries due to past mortality and ongoing health disparities. Values in the upper 60s or mid-70s would imply longer lifespans than what current mortality data show for South Africa, while a figure around the mid-50s would understate the gains from public health advances. So 62.8 years best reflects the typical birth-year life expectancy for South Africa in recent years. Remember this is birth-life expectancy, not how long a person currently aged a particular age is expected to live.
