What it means

Put people or households in order by net worth. A percentile marks a point on that ranking: the 90th percentile is the wealth level reached by roughly 90% of those counted, with roughly 10% above it. Reports may also talk about the people in the 90th percentile, meaning one hundredth of the ranked group around that point. Check whether a report ranks individuals or households, and what it counts as wealth.

Example

If the 90th-percentile cut-off in a made-up survey is £500,000, roughly nine in ten of those ranked have net worth at or below £500,000. This is a cut-off, not the average wealth of the richest tenth.

Why it matters

It lets you see where a wealth figure sits in a wider group without assuming that everyone near the top has similar amounts.
