What is the life expectancy at birth for all Koreans according to the material?

• A. 83.17
• B. 75.0
• C. 90.0
• D. 80.0

Answer: (A)

Life expectancy at birth is the average number of years a newborn would live if current mortality rates at each age stayed the same over time. It’s a broad measure of how well a population is doing in terms of survival, reflecting health, living conditions, and access to care. In the material, the life expectancy at birth for all Koreans is 83.17 years. This figure represents the combined expectation for the two sexes and serves as the reference point for Korea’s overall mortality profile in that source. The other values listed do not match the data provided, so 83.17 years is the best choice.
