How well do you think you know your local area? You might be surprised.
The ONS has released a clever little tool that quizzes you on your knowledge of your local area.
If you live in England or Wales, just pop in a postcode and then make your best guess on everything from the religious beliefs of your neighbours to how many are paying a mortgage on their home.
It's based on data from the 2011 census.
Everyone in the Full Fact office has given it a go, and none of us were able to score much more than 50%.

What really surprised us is the diversity of the ways in which we went wrong - some of us knew almost exactly how many children lived in our areas but were taken aback by how many didn't own a car. For others it was the complete opposite.
It's a great example of how official statistics can be communicated in an engaging way.
