Bottom 50% household wealth share
Share of total US household wealth held by the bottom 50% of households.
Reading
The floor the sovereign math rests on. The five-year equity bull run was almost entirely a wealth event for the top quintile.
Thresholds
- watch2 — falls below 2% — a structural break with the postwar distribution
Context
Why this matters
The wealth-share series tells you what proportion of the population has any meaningful buffer against shock. A bottom-50% share around 2.5% means half the country shares the same fraction of total household wealth as a small number of individuals at the top. This is the floor on which the political economy sits — every policy response to a downturn, an entitlement transition, or an inflation shock has to operate inside the consent of a population without buffers.
Who watches this
- Emmanuel Saez & Gabriel Zucman (UC Berkeley) — built and maintain the underlying capital-income methodology
- Thomas Piketty — Capital in the Twenty-First Century placed wealth concentration at the centre of the long-run picture
- Joseph Stiglitz — uses the series prominently in his post-2008 policy work
- Anat Admati (Stanford) — applies it to argue the financial-sector structure amplifies the trend
- The Fed's own Distributional Financial Accounts team — the official US series
Recent history
The share fell to ~1.5% post-GFC and has recovered only to ~2.5% despite a decade-plus of asset-price appreciation, because the bottom 50% holds essentially no equity exposure. The 2020–2025 equity bull run widened the gap further.
What would change my read
A sustained narrowing — say, the bottom-50% share returning to its 1989 starting level of around 3.7% — would require either a meaningful policy redistribution or a deep equity drawdown that compressed the top-decile share faster than it hit the bottom-half's (small) asset exposure. Neither is the base case.
