US Demographics by State

Each state page shows: total population, median household income, median age, total number of households, average household size, and a list of major cities. Data comes from the US Census Bureau American Community Survey (ACS) 5-year estimates for 2022.

California is the most populous US state with approximately 39 million residents. Texas (29M) and Florida (22M) rank second and third. Wyoming, Vermont, and Alaska are the least populous states, each with fewer than 750,000 residents.

Maryland consistently ranks as the state with the highest median household income, followed by New Jersey, Massachusetts, and Connecticut. These states have high concentrations of high-income workers in government, finance, and technology sectors.

The American Community Survey is mailed to about 3.5 million addresses each year. It's mandatory to respond. The 5-year estimates used here pool data from 2018-2022 surveys, providing a more reliable picture than any single year. Response rates are typically 85-95%.
