How is world population calculated? And how accurate is the number? Is it possible that the number can be entirely wrong?
In: Other
The truth is, we actually don’t know how accurate the estimate is because we’d have to know the near exact number in a sufficiently large representative area to compare it with the estimate. My guess is it can be several percentage points off, though certain undercounts (mentioned by others) can potentially be compensated by the folks with multiple citizenships that presumably are reported by each home country.
