What does underreport mean?
Underreport means to report a number, amount, or level that is smaller than the actual one. It is especially common in discussions of business, government, public health, crime, and statistics, where accurate reporting is important for regulation and public understanding. For example, a company that reports less income than it earns has underreported its earnings; an agency that fails to record all the cases it receives has underreported those cases. The word can carry a critical or accusatory tone because intentional underreporting suggests deception or concealment, although it can also describe an accidental omission or counting error. As a noun, an underreport is an account that understates the reality. The related verb underreported describes a completed act, while underreporting names the activity itself. Together, these forms are useful for describing a recurring problem in which official figures and real-world conditions do not match.

In statistics and public health, an underreport can make a serious problem appear far smaller than it really is.

Where does underreport come from?
Underreport is an English compound formed from the prefix under- and the word report. The prefix under- comes from Old English and means beneath or less than, while report entered English through Old French from Latin reportare, meaning to carry back or bring back. The compound developed the meaning of reporting something at a level below the actual one. Its relatives reporter, reportage, and reportorial belong to the same established reporting-related vocabulary.
