London mayoral election 2012: get the key data you need

London's mayoral election is only three weeks away. But the mayor of a city with a population of over 7.8m people wields real national power. Whether you're gunning for Boris Johnson, Ken Livingstone, Brian Paddick or Jenny Jones - or one of the other candidates, where do you find the key data? We wanted to provide one place to explore and discuss the key facts around the big London issues, such as health, crime, economy, employment and population in the capital. We've extracted those datasets for you from top sources: including the London Datastore , the Office for National Statistics and other government sources. Here you will find maps of poverty , unemployment data , crime statistics, population figures , previous election maps - and a whole lot more. When the results come in - we will have those in a format you can use, too. It's just a start - and we will be adding to it every day. What else would you like to see?
