Government inspectors are to ask us intimate questions about our sex lives, it was revealed.
More than half a million people every year will be asked about their past and present sexual partners, contraception and how long couples have lived together before marriage.
The 2,000 questions are part of the Integrated Household Survey, and the responses will be logged with respondents’ names and addresses.
Civil servants insist that the sensitive personal information will be made anonymous once the files arrive at the Office of National Statistics, where they will then be held on a secure server.
But campaigners last night branded the survey “intrusive” and another example of Labour’s “surveillance state”.
The survey will cost £3.5 million to carry out each year and will see inspectors randomly visit up to 200,000 homes to question each occupant.
They will ask 35 questions on contraception alone, covering vasectomies, the pill and if respondents have ever used the “morning after” pill.
Other intimate questions include the exact dates when previous relationships ended, precise monthly earnings and details of any second jobs or bonuses.
Investigators will also ask about the health of any children in the household.
One insensitive question asks: “Have you ever had a baby – even one who lived for a short time?”
Interviewers are then told: “Exclude: Any stillborn; include: Any who lived for a short time.”
