2 Introduction to the Scottish Household Survey
2.1 This bulletin provides further analyses of transport related questions, asked by the Scottish Household Survey ( SHS) from 1999 to 2008.
2.2 The SHS is a survey of private households and does not cover some sections of the population - e.g. does not collect information about many students living in halls of residence.
2.3 The SHS collects a wide range of information with questions asked of either:
- the household as a whole
- one randomly-chosen adult (aged 16 or over) member of the household
- one schoolchild (if there is one in the household)
- Highest Income Householder
The results are then weighted to take account of differences in selection probabilities.
2.4 The main changes to this edition include
- the addition of two new tables on Park & Ride facilities [Table 18, Table 19].
- the addition of information on the Young Persons' Concessionary Travel Scheme
2.5 Where questions were asked of small numbers of individuals (due to sub sampling or the particular relevance of a question) results are produced by combining years to increase the sample size and therefore the reliability.
2.6 The data was extracted from the SHS database in autumn 2009 and does not take into account any subsequent revisions to the data.
2.7 Results are subject to sampling variability and care should be taken when interpreting year-on-year changes. Table 36 shows the confidence limits for the results and section A.18 describes how these should be used.
