Scottish Health Survey 1998
Synopsis:
The survey was designed to provide a nationally representative sample
of the population of Scotland aged between 2 and 74 living in private
households. Residents living in institutions (who tend to be older than
people in private households) were excluded from the survey.
The survey is based on ‘a stratified, multi-stage
random sample’. This design involved first ordering all postcode sectors
in Scotland by region and the Carstairs index of deprivation and then
systematically selecting 312 of them. Within these sampling points,
15,288 addresses were selected from the Postcode Address File (PAF). At
each residential address up to three households were selected randomly
by interviewers, though selection of more than one household was rare.
Within each household, one person aged 16-74 and up to two children aged
2-15 were selected randomly to be included in the survey.
One aim of the Health Survey is to compare regions
within Scotland. Hence, regional sample sizes have to be sufficient for
reliable comparisons to be made. It was not feasible to enlarge the
total sample to interview a sufficiently large sample in every Health
Board area. Therefore, for the purposes of the survey, seven ‘regions’
were defined by aggregating (mainly) contiguous Health Boards:
Highland & Islands (Orkney, Shetland, Western
Isles)
Grampian & Tayside
Lothian & Fife
Borders, Dumfries & Galloway
Greater Glasgow
Lanarkshire, Ayrshire & Arran
Forth Valley, Argyll & Clyde
In order to provide sufficient sample sizes within
each region, the two least populated regions - Highland & Islands and
Borders, Dumfries & Galloway - were slightly over-sampled, while the
other five regions were sampled (roughly) in proportion to their
population size.
