What Economic Inequality Measures
Economic inequality refers to the uneven distribution of wealth, income, and net worth among individuals or groups. It captures gaps in earnings, asset ownership, and financial power across households, regions, and countries. The most common indicators are the Gini coefficient, the share of income held by the top 1%, and the ratio of median wealth to average wealth. The World Inequality Database and the Federal Reserve's Survey of Consumer Finances provide the latest publicly available figures on these metrics Federal Reserve wealth distribution data.
Wealth inequality is typically wider than income inequality because assets accumulate over time and compound returns favor those who already hold large portfolios. Net worth includes real estate, financial assets, and business equity minus debts, so it reflects both current earnings and past savings. In the United States, the top 1% of households own a disproportionate share of total net worth, while the bottom 50% hold a much smaller share. The Congressional Budget Office regularly publishes reports on the distribution of household income and wealth CBO income and wealth distribution.
Global and Country-Level Rankings
Cross-country comparisons show that market economies with high capital concentration tend to have larger gaps in wealth and income. The World Inequality Report and OECD data rank countries by income share, Gini coefficient, and wealth concentration. Nordic countries often rank lower on inequality metrics due to progressive taxation and broad social transfers, while some emerging economies show high concentration of wealth among a small elite. The latest available data from the World Inequality Lab and the OECD show persistent gaps between the top and bottom income deciles OECD income inequality data.
In the United States, the top 10% of earners capture a large share of national income, and the top 1% hold a significant portion of total financial wealth. The Federal Reserve's Distributional Financial Accounts track changes in net worth across percentile groups, showing that asset price increases can widen gaps quickly. The latest release of the Survey of Consumer Finances shows that the median family's net worth remains far below the mean, reflecting the concentration of holdings in equities and real estate among higher-wealth households Federal Reserve Survey of Consumer Finances.
Drivers and Real-World Examples
Key drivers of economic inequality include returns on capital outpacing wage growth, access to education and credit, and differences in inheritance and intergenerational transfers. Companies such as Tesla and SpaceX have created concentrated wealth for founders and early investors, illustrating how equity ownership in high-growth firms can amplify net worth gaps. Public filings and stock ownership reports show that a small number of insiders and institutional holders control large stakes in these companies, while most households hold limited direct equity exposure SEC filings and ownership data.
Policy responses to inequality include progressive income taxes, capital gains taxes, estate taxes, and social safety nets that affect after-tax income and net worth. Central bank policies, such as interest rate decisions and asset purchases, also influence wealth distribution by affecting asset prices and borrowing costs.
