Question(s) from the Census form

For each female, how many babies has she ever given birth to?

How this variable is created

Data for this variable is captured automatically from written numeric responses, or the 'None' response category on the paper form. All numeric responses are accepted as reported.

History and changes

This question was first asked in the 1981 Census.

For 2016, an instruction on the form to include live births only was removed, due to evidence of the sensitivities of this question which cannot be overcome effectively in a self-report questionnaire. This instruction was previously included to collect births information according the United Nations Standard.

No changes have been made for 2021.

Data use considerations

The data may include a small proportion of persons with unusually high numbers of children ever born, as all numeric responses are accepted as reported.

For the Census online form, females aged 15 years and over were asked this question. Male respondents and people who responded only with non-binary sex were not asked this question.

The non-response rate for Number of children ever born (TISP) was 6.7% in 2021. This is a decrease from 8.0% in 2016.
