What it means

Wealth is concentrated when a small group owns a large share of the total. One way to show this is to ask what share belongs to the wealthiest 10% or 1%. The answer depends on what counts as wealth and whether people or whole households are being compared. Income is different: it is money coming in over time, rather than wealth already owned.

Example

Imagine 100 households whose combined net worth is £10 million. If the wealthiest 10 households together own £6 million, the top 10% hold 60% of the total wealth in this made-up group.

Why it matters

An average wealth figure can rise even if most households see little change. Looking at who holds the wealth adds useful context.
