Rightmove has launched an ‘alternative census’ into people’s habits.

It asks about your drinking, your exercise regime and whether you have been on a diet in the last 12 months.

One question is about your wedding day and whether you consummated your marriage.

Aimed at consumers, people who complete it are given various options to tick, including one saying that they prefer not to answer.

The census – which offers the chance of winning £100 worth of Amazon vouchers – also asks how many hours you sleep, whether you prefer cats or dogs, how many hours you work, whether you are happy in your current relationship, how many close friends you have, and what you would do if you won the lottery.

Other questions ask if you are happy in your job, support a football club and if so which one, and whether you would rather be rich, happy or outrageously good looking.

The questionnaire, which contains no questions about property, was sent out yesterday to people registered on the Rightmove website.

It ends by asking people for the areas they live in, the first part of their postcode, plus, if they want to be in with a chance of winning vouchers, their email addresses.

It was seen by one agent who was outraged: “Why on earth is Rightmove asking these sort of questions? It stops short only of asking people what their sexual preferences are.

“At first glance, it reads as though Rightmove is setting up a dating agency.

“However, I strongly suspect that the reality is they are gathering consumer information, so that they can sell their database on to commercial firms.”

He said: “They are extraordinary questions to put to my applicants and unlikely to imbue them with confidence that Rightmove is a responsible and serious company dedicated to help them in the largest financial transaction in their lives.”

A spokesperson for Rightmove told Eye: “It’s for some consumer PR we’re planning for the future. We decided to come up with loads of questions to see which ones give the most interesting results for stories.

“Obviously it’s all kept completely anonymous and people have the option to tick ‘prefer not to say’ if they don’t want to answer.”
