Coverage errors arise from failure to cover adequately all components of the population being studied. Incomplete sampling frames often result in coverage errors.

Coverage errors are due to divergences between the target population and the frame. Coverage errors include over-coverage, under-coverage and misclassification (Eurostat, Quality Glossary).

Coverage error is the error in an estimate that results from failure to include specified units in the conduct of a survey (undercoverage), and inclusion of some units erroneously either because of a defective frame or because of inclusion of unspecified units or inclusion of specified units more than once in the actual survey (overcoverage). (Statistical Policy Working Paper 15: Quality in Establishment Surveys, Office of Management and Budget, Washington D.C., July 1988, page 44).
