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.

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.
There are no significant issues that users should be aware of.

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.
