Prosecution and fines for those who delay
There's a warning for those who have not yet returned their census forms they are set to face prosecution and a fine of up to £1,000.
The Census Office describes it as a 'small number of Island householders' who have yet to do the forms.
The office says anyone who hasn't done a form yet now has one last chance to do so.
If they still have their online code they can complete the form themselves by visiting gov.im/census, or they can call 685700 and the Census Office will take their return over the phone.
There's also a call for parents to make sure their children were put on the forms.
