Up 5 Percent—or 5 Percentage Points?

The explanation

These two phrases can describe very different changes.

Suppose support for an imaginary proposal rises from twenty percent to twenty-five percent. The difference is five percentage points. But relative to the original twenty percent, the increase is twenty-five percent. Five divided by twenty equals one quarter.

A headline saying support rose twenty-five percent can sound enormous, even though seventy-five percent still did not select that option. The math can be correct while the impression is incomplete. Always ask whether a change is expressed in points or relative percent.

Keep the original and new values beside every percentage claim. That makes the calculation checkable and prevents a dramatic phrase from replacing the actual result. Our example is fictional, not a real poll.
