US Income Inequality by the Numbers
The latest available data shows the top 10% of US earners capture roughly 48% of total national income, while the bottom 50% holds about 13%. The Gini coefficient for household income stands near 0.49, indicating high inequality. These figures are drawn from the Census Bureau and the Congressional Budget Office, which regularly publish updated income distribution tables Forbes.
Real median household income reached a record level in nominal terms, yet growth has been unevenly distributed. The top 1% of households now hold a larger share of total income than the bottom 50% combined, a gap that has widened over the past three decades. Wage growth for the bottom quintile has lagged far behind gains at the top, even during strong labor markets Census Bureau.
Wealth Concentration and Asset Ownership
US wealth inequality is even more pronounced than income inequality. The Federal Reserve’s Survey of Consumer Finances shows the top 1% of families own roughly 30% of all household wealth, while the bottom 50% hold less than 3%. The median net worth for the top 10% exceeds $1.7 million, compared with under $10,000 for the bottom 50% Federal Reserve.
Stock market ownership remains highly concentrated. The top 10% of families by income own about 89% of all equities held directly or indirectly through retirement accounts and trusts. This concentration amplifies wealth gaps because equity returns compound over time, benefiting those who already hold large portfolios. Companies such as Tesla and SpaceX have created substantial new wealth for founders and early investors, further widening the top of the distribution SEC.
Drivers and Current Policy Debates
Key drivers of US economic inequality include globalization, automation, declining union membership, and tax policy changes that favor capital gains and carried interest. The top statutory individual income tax rate has fallen from over 70% in the 1970s to 37% today, while the effective tax rate for the wealthiest households often remains lower than for many middle-income families Tax Policy Center.
Recent legislative proposals focus on raising the corporate tax rate, expanding the Child Tax Credit, and strengthening IRS enforcement to reduce the tax gap. The Congressional Budget Office projects that current policy trajectories will continue to push the after-tax income share of the top 1% higher over the next decade. Meanwhile, the Federal Reserve monitors inequality as part of its financial stability mandate, noting that extreme wealth concentration can limit broad-based economic resilience Federal Reserve.
