What percentage of the world's population is in PACAF's area of responsibility?

• A. 40 percent
• B. 50 percent
• C. 60 percent
• D. 70 percent

Answer: (C)

The main idea is understanding how population is distributed across PACAF's area. The Pacific Air Forces AOR covers the Asia-Pacific region, where most of the world’s people live. Asia alone accounts for about six-tenths of humanity, and when you add the populations of the Pacific nations and islands, the combined total sits around 60% of the world’s population. That’s why the best match is 60 percent. The other options would under- or overstate the share of people in this area, given how densely populated Asia and nearby regions are.
