collected include the total number of occupants of
the household, net household income, weekly
expenditure on food, energy
(electricity / gas / oil etc.), entertainment and
travel, whether or not the family have a
car, whether or not they have a subscription
TV service, their internet
connectivity status (none, fibre, non-fibre), whether or not the
family have private health insurance and whether
