Approximately one in five households in the United States earn more $100,000 annually, as of 2010, which is the last year that the U.S. Census Bureau has published data regarding income, according to National Public radio. That figure represents around 19.9 percent of all households. Notably, the U.S. Census Bureau defines a household as all the people occupying a house or apartment.
One in four of the 114.6 million households in the U.S., which is around 24.9 percent of households, make less than $25,000 per year while around one in three households, or 30.1 percent of households, make between $50,000 and $100,000 annually.
The median income in the U.S. is roughly $50,000 per year, and around half of the households in the country made less than $50,000 per year; around half made more. The annual income includes both money earned as income and money derived from benefits, including subsidized housing and food stamps that are generally targeted at citizens with the lowest incomes. Capital gains, dividends and rent incomes were excluded from the total income amounts.
Income varies widely by state. The states with the lowest median incomes were Mississippi ($36,851), West Virginia ($38,218), Arkansas ($38,307), Kentucky ($40,062) and Alabama ($40,474). The states with the highest incomes include Maryland ($68,854), New Jersey ($67,681), Alaska ($64,576), Connecticut ($64,032) and Hawaii ($63,030).
