The groups of activities most likely to be non-observed are those that are underground, illegal, informal sector, or undertaken by households for their own final use. Activities may also be missed because of deficiencies in the basic statistical data collection programme.

The groups of activities are referred to (in the NOE Handbook) as the problem areas. Activities not included in the basic data because they are in one or more of these problem areas are collectively said to comprise the non-observed economy (NOE).
