Frequently asked questions
What's the difference between percent and percentage points?
Going from 5% to 7% is a 2 percentage-point rise but a 40% relative increase — news headlines often confuse these.
Why isn't a 50% fall reversed by a 50% rise?
Because the base changes. After a 50% drop you need a 100% rise to get back to where you started.
