*Last 7 days = rolling 24 hours * 7 days. New articles pop on as they are published, old articles drop off the end and time moves on. In other words these values will change throughout the day.
**Online Only is content that's published digitially and has never even seen a whiff of print in either the Guardian or the Observer. Guardian and Observer content is also published online, so Online Only + Guardian + Observer = Total Online Content.
