Term Definition
Coverage error,

Survey error (variance and bias) that is introduced when there is not a one-to-one correspondence between frame and target population units. Some units in the target population are not included on the sampling frame (undercoverage), some units on the sampling frame are not members of the target population (out-of-scope), more than one unit on the sampling frame corresponds to the same target population unit (overcoverage), and one sampling frame unit corresponds to more than one target population unit.
