UN population series; million people, 1950 versus 2021.
Population in Cameroon covers 1950-2021 on a million persons basis. The comparison uses 2 observations from UN population series and Cameroon estimates. The UN series rises from 4.47 million people in 1950 to 27.20 million in 2021. The 2024 INS-based estimate uses a different basis and is not part of this UN-series comparison.
| Rank | Entry | Value | Period |
|---|---|---|---|
| 1 | Population | 4.47M | 1950 |
| 2 | Population | 27.20M | 2021 |

Evidence: Supports the published values, periods and status labels used for population in Cameroon.
The lack of a census since 2005 creates a wider current-estimate spread, handled in a separate held candidate.
The statistic uses two final observations from one UN population series and avoids mixing the separate INS-based current estimate.
All directly compared values are kept on the source, period and unit basis stated in their rows; mixed-status or mixed-denominator support metrics are explicitly separated.
