Internal migration is the movement of people from one defined area to another within a country.
Data gathered on where the person usually lived one year ago and five years ago is used together with information from Question 8 on usual residence, to study internal migration. Information on internal migration also contributes to the calculation of intercensal and postcensal population estimates.
Since 1971 people have been asked to provide the full address of their usual residence five years ago. A question on usual residence one year ago has been included since 1976. In 1991, respondents were asked only for their state of usual residence one year ago and for their full address five years ago. Full address of usual residence for both one year ago and five years ago has been asked since the 1996 Census.
The following questions are from the paper 2016 Census Household Form.
