I have been looking at the GHS2000/2001
(client1). There are two variables fathsmk mothsmk referring to the bands
of cigarettes smoked by father and mother. The dataset contains 13250 cases
with around 3450 respondents were smokers. However, only 156 men and 93 women
reported parents smoking (including never smoked, ex-smoker etc). I went to
the questionnaires and cannot find the question that asks this. I thought
that this might be asked of the 16/17 year olds but a check showed that of
those with valid answers of parental smoking, the age range spreads to over
60. So could you please tell me:
(1) who was this question addressed
to
(2) where is this question located
(3) if derived variable, what is the basis of this derivation
(4) on the whole, how reliable is the information contained in the two variables.
I have emailed ONS who have sent
the syntax for the smoking variables you enquired about (see below). The variables
are derived.
