Seven million households which have not completed and returned the census in England and Wales are being warned that they face a visit from officials.Among those with something to hide, the smart ones have already lied.
Some 29,000 census collectors will begin visiting householders who have not returned their questionnaire to help, or persuade, them to complete it.
Completing the census is compulsory and not doing so could mean a £1,000 fine.
The north east of England has seen 75% compliance, compared to London which has the lowest compliance rate at just 60%.
The ONS said it had anticipated that London would be a "challenging area" and almost 6,000 collectors would be door-knocking across the city.
