Sector of ownership


The 'sector of ownership' variable identifies the sector of the economy in which people who are over 15 years of age are employed.

The classification criteria for 'sector of ownership' are based on the partitioning of organisations and businesses in the economy into institutional sectors. Organisations and businesses are categorised according to who they are owned by and their function, control and behaviour. The sector of ownership classification has four categories:

  • central government
  • local government
  • private
  • not stated.

Relationship to questionnaire(s)

This variable 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 5.7 percent.

The 2001 non-response rate was 4.8 percent.

Quality Management Strategy priority level

Sector of ownership 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

Limited data by sector of ownership is available from the Quarterly Employment Survey (QES) and the Linked Employer-Employee Data (LEED) project, but there are major differences between the census and these other sources, particularly regarding scope and coverage (for example the QES is a survey of businesses not households) and so caution should be exercised in any attempted comparisons.

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 sector of ownership.
  • There are some inconsistencies between this and some other employment variables (especially with the status in employment variable) due to respondent error. For example, there are a number of cases where people with a sector of central or local government have a status in employment of unpaid family worker, employer or self-employed (which should not occur). This is due to sector of ownership being coded independently of status in employment.
  • 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 industry were limited to 120 characters.
