Industry

Definition

'Industry' is the type of activity (undertaken by the organisation, enterprise, business or unit of economic activity) in which a person aged 15 years and over is employed.

Relationship to questionnaire(s)

Data on industry comes from questions 37, 38 and 39 on 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 4.1 percent.

Quality Management Strategy priority level

Industry is a supplementary variable.

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

Supplementary variables do not fit directly in 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 issues affecting the comparability of this data with the 1996 and 2001 Census data.

Comparability with other data

The Quarterly Employment Survey (QES), the Household Labour Force Survey (HLFS) and the Linked Employer-Employee Data (LEED) project publish employment data by industry of employer. There are a number of important differences between these data sources and the census, which mean that direct comparison is not always possible, particularly below the national level and specifically for cross-classifications of variables. The differences between the three data sources include differences in scope, coverage (including under- and over-coverage), timing, non-response, editing practice, question wordings and method of delivery (self administered versus interviewer administered). Additionally, both the QES and the HLFS are sample surveys and LEED is produced using administrative data. Statistics NZ can assist data users in determining the best data source for their particular data need.

Significant issues

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

Other things to be aware of

  • Employers' names and addresses are matched against Statistics New Zealand's Business Frame in order to code industry.
  • Data from the 2006 Census was dual coded to both the 1996 and 2006 Australian and New Zealand Standard Industrial Classifications (ANZSIC). Data has been output for all time series data (ie that which includes data from 2001 and/or 1996) using the ANZSIC 96 classification. For cross-sectional data (ie 2006 only) ANZSIC 06 classifications were predominantly used.
  • 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:
    • On the Internet, the text fields for 'name of business/employer' and 'main activity of business or employer' were limited to 120 characters.
    • On the Internet, it was only possible to give text responses for the workplace address question if 'work away from home' was marked. When forms were completed on paper it was possible to give a text response but not mark the 'work away from home' tick box.
