Approximately what percentage of the world's population lives in unreached peoples?

• A. 40%
• B. 60%
• C. 10%
• D. 25%

Answer: (A)

The main idea here is the share of the world’s population that lives in unreached peoples—groups with little or no access to the gospel and no viable indigenous church-planting movement.

Unreached peoples are typically defined as communities where evangelical believers are a very small presence (often less than about 2% of the population) and there isn’t a self-sustaining church-planting effort. When you look at where these groups are concentrated—large parts of Asia, the Middle East, and parts of Africa and the Pacific—the global total falls around forty percent of people. That’s why forty percent is the best answer: it reflects the substantial portion of humanity still outside an accessible, self-reproducing gospel presence.

The other options don’t fit because they either overstate or understate the scale of unreached populations relative to the best-supported estimates. Understanding this helps explain where missionary focus and resource planning are often directed in strategy discussions.
