The richest state in the United States depends on how you measure wealth, but by most metrics, the same handful of states consistently land at the top. Massachusetts leads the nation in median family income at $178,524 for a family of four, while New York ranks first in GDP per capita. New Jersey has the highest concentration of millionaire households. These three states, along with Maryland, Connecticut, and Washington, dominate nearly every wealth ranking.
Top States by Household Income
Median family income is one of the most straightforward ways to gauge how much money residents actually bring home. Based on U.S. Census Bureau data, the five highest-earning states for a family of four are:
- Massachusetts: $178,524
- New Jersey: $168,127
- Maryland: $166,173
- Connecticut: $159,934
- Washington: $156,567
These figures reflect raw income before adjusting for the cost of living, which matters a lot. A family earning $178,000 in the Boston suburbs faces significantly higher housing costs than a family earning $120,000 in a lower-cost state. Still, as a measure of earning power, median income captures how much money flows into households, and these five states consistently outpace the rest of the country by tens of thousands of dollars.
Top States by Economic Output
GDP per capita measures how much economic value a state produces for each resident. It captures not just wages but the total output of industries operating within state borders. By this measure, the top states in 2022 were New York, Massachusetts, Washington, and California, all of which benefit from concentrations of high-value industries.
New York’s economy is driven heavily by finance and insurance. Massachusetts draws from professional and scientific industries, including biotech and higher education. Washington benefits from its tech sector and global trade, while California’s $3.2 trillion economy (the largest of any state) runs on real estate, professional services, and technology. Total GDP and per-capita GDP tell different stories: California and Texas rank first and second in total economic output, but their large populations push per-capita numbers lower than smaller, high-income states like Massachusetts.
Where Millionaires Are Most Concentrated
Another way to define “richest” is to look at where wealthy households cluster. New Jersey has the highest concentration of millionaire households in the country, with 9.76% of households holding $1 million or more in investable assets. That figure excludes real estate, employer retirement plans, and business partnerships, so it reflects liquid financial wealth rather than home equity.
Maryland comes in just behind at 9.72%, followed by Connecticut at 9.44%, Massachusetts at 9.38%, and Hawaii at 9.20%. California ranks seventh by concentration (8.51%), but because of its sheer population, it has by far the most millionaire households in raw numbers: over 1.1 million.
The pattern is clear. States clustered in the Northeast corridor, particularly those within commuting distance of New York City and Washington, D.C., have outsized concentrations of wealth. Proximity to major financial centers, federal government jobs, and knowledge-economy employers pulls incomes and asset levels well above national averages.
How Cost of Living Changes the Picture
High incomes don’t always translate into high purchasing power. The Bureau of Economic Analysis publishes regional price parities that measure how expensive each state is relative to the national average. A score of 100 means prices match the national level. California’s score of 110.7 means goods and services there cost roughly 11% more than the national average. Hawaii sits at 110.0, and New Jersey at 108.8.
Housing is where the gap gets dramatic. California’s regional price parity for housing rents is 154.3, meaning rents run about 54% above the national average. By contrast, lower-cost states can have housing price parities below 60. So a family earning $170,000 in New Jersey is paying a significant premium for housing compared to a family earning $130,000 in a state where the cost of living sits below the national average. After adjusting for these differences, some high-income states lose their edge, while states with moderate incomes but low costs can offer comparable or better buying power.
This is why personal finance discussions distinguish between income and real purchasing power. If your goal is to understand where people earn the most, Massachusetts and New Jersey top the list. If you want to know where a dollar stretches the furthest, those same states may not feel as wealthy to the families living there.
Which States Are Growing Fastest
Wealth isn’t static, and some states are gaining ground faster than others. Real personal income (income adjusted for inflation and regional price differences) increased in 46 states in 2024, with a national average growth rate of 2.9%. California led the country with 5.5% real personal income growth, while North Dakota was one of the few states to see a decline, falling 2.2%.
Fast income growth doesn’t necessarily mean a state is wealthy today, but it signals where economic momentum is building. States with expanding tech sectors, growing populations of high-skill workers, or booming industries tend to see the sharpest income gains over time.
So Which State Is the Richest?
If you’re looking at a single answer, Massachusetts has the strongest overall claim. It ranks first in median family income, second in GDP per capita, and fourth in millionaire concentration. New Jersey is a close competitor, leading the nation in millionaire density and ranking second in household income. Maryland and Connecticut round out the top tier by nearly every measure.
The “richest” label shifts depending on whether you prioritize raw income, economic output, accumulated wealth, or purchasing power after living costs. But the Northeast corridor from Maryland to Massachusetts, with Washington state as a West Coast outlier, consistently produces the highest-earning, most asset-rich households in the country.
