What does underreporting mean?
Underreporting means reporting less than the true amount or failing to report something that ought to be disclosed. It is used especially in discussions of crime, workplace injuries, disease cases, survey responses, income, and institutional records. For example, authorities may refer to the underreporting of sexual assault when many incidents are not formally recorded, while researchers may identify underreporting when survey respondents conceal their circumstances. The word is commonly formal and can carry a serious implication: incomplete figures may conceal the extent of a problem and lead to inadequate policy or resource allocation. Underreporting does not necessarily mean that the reported information is wholly false; its defining feature is that too little is reported. It differs from general misreporting, which may involve exaggeration or distortion as well as omission. The word is useful because accurate public discussion depends on reliable records, and underreporting identifies one of the main ways recorded totals can understate real-world conditions.
The practice of reporting a number, amount, or incident as smaller than it actually is, or of failing to report something that should have been disclosed.
"Health officials warned that underreporting of the disease had made the outbreak appear less severe than it was."
Usually uncountable, though it may be modified by words such as widespread, chronic, or suspected.

Typically transitive and used in contexts involving records, statistics, disclosures, or official reports.

When the true count is higher than the official count, the gap is underreporting.

Where does underreporting come from?
Underreporting is a modern English compound formed from the Germanic prefix under- and the established English word reporting. Reporting derives from report, which entered Middle English through French and ultimately Latin reportare, meaning “to carry back,” from re- and portare, “to carry.” English derivatives such as reporter and reportage share this root, while portable retains the underlying Latin verb portare.
