Definition
The number of people counted by a census who should not have been counted or who were counted more than once. It is usually expressed as a percentage of what should have been the complete count rather than as a percentage of what was counted.

Net census undercount is the difference between census undercount and overcount.

Example
The 1996 and 2001 post-enumeration surveys estimated (gross) census overcount of the New Zealand population to be 0.2 ± 0.1 and 0.6 ± 0.1 percent, respectively (sample errors at the 95 percent level).
