2.84 Definition:
The sub-sector others consists of persons living permanently in institutions.
Persons living permanently in institutions are classified separately because
the criterion of the largest source of income does not allow a meaningful
classification of these persons in one of the foregoing sub-sectors.
2.85
If the main income source of the household as a whole is not available for
sectoring purposes, the income of the reference person constitutes the second-best
characteristic to be used for classifying purposes. The reference person of a
household is normally the person with the largest income. If the latter
information is not available, the income of the person who states that he/she is the
reference person may be used for sub-sectoring households.
2.86
However, other criteria may be appropriate and needed for different kinds of
analysis or as the basis for policy-making, e.g. breakdown of households as
entrepreneurs by activity: agricultural households; non-agricultural households
(industry; services).
