Definition

'Main means of travel to work' is the method by which the respondent, aged 15 years and over, travelled the longest distance to work on 7 March 2006, for example by bicycle, bus, walking or jogging.

Relationship to questionnaire(s)

Data on main means of travel to work comes from question 41on the individual form (PDF 395kb).

Subject population

The subject population is the people, families, households or dwellings to whom the variable applies.

The subject population for this variable is the employed census usually resident population aged 15 years and over.

Non-response rate

The 2006 non-response rate was 3.7 percent.

The 2001 non-response rate was 3.5 percent.

Quality Management Strategy priority level

Main means of travel to work is a supplementary variable.

The Census Quality Management Strategy assigns a priority level to all census variables.

Supplementary variables do not fit in directly with the main purpose of a census, but are still of importance to certain groups. These variables have third priority in terms of effort and resources.

All data must meet minimum quality standards in order to make it suitable for use.

Comparability with 1996 and 2001 Census data

There are no significant issues affecting the comparability of this data with the 1996 and 2001 Census data.

There has been a change in the way that multiple responses are treated. In 2001 the first marked box was coded when a multiple response was given, whereas in 2006 multiple responses were coded to the new 'response unidentifiable' category. However, this change has made little or no impact on the comparability of the data, or its distribution and quality, as the number of multiple responses to this question is very low.

Significant issues

Other things to be aware of

  • Inconsistencies can occur when comparing 'worked at home' counts from the 'main means of travel to work' variable with 'work at home' counts from the 'workplace address' indicator variable. This is due to differences in the reference period, as the 'workplace address' question relates to the week ended 5 March 2006, whereas the 'travel to work' question relates only to the day of 7 March 2006.
  • Responses in the text field for this question are coded to 'other'.
  • All census data was subject to considerable checks (including edits) during processing and evaluation, to ensure that it meets quality standards and is suitable for use. These checks were applied to data supplied both on paper and on Internet forms. In addition to these quality checks, the Internet form had built-in editing functionality that directed respondents to the appropriate questions and ensured that their responses were valid. As a result of this, data from Internet forms may be of higher overall quality than data from paper forms. The significance of this will depend on the particular type of analysis being done.
  • There were differences between how the forms were completed on the Internet and on paper for this variable:
    • The Internet form allowed only one response to be selected for the main means of travel to work question. If a further response was selected, the response given previously disappeared. Multiple responses to this question were possible when forms were completed on paper.
