The accuracy1 of population statistics will depend among other factors on the completeness2 of the operation on which they are based. Inaccuracies may be due to omission3, under-registration3 or under-enumera-tion3, to multiple counting4 or over-registration4, to misreporting5 of a characteristic such as age, or to tabulating errors6. Such inaccuracies are sometimes detected by post-enumeration tests7 or quality checks7. Occasionally certain questions are not answered or insufficiently answered and this may lead to considerable inaccuracy, the incidence of which is indicated by the frequency of the class (130-9) designated as not stated8 or unknown8.
- 1. accuracy n. — accurate adj.

The terms "complete" and "completeness" are used here to express the absence of omissions, under-registration etc. The same terms were also used (202-4*) as opposed to sampling procedures.
