The statistic shows the median household income in the United States from 1990 to 2015. The median household income was 56,516 U.S. dollars in 2015, a slight percent increase from 2009. Since 2007, the median household income has declined from 57,357 U.S. dollars and is far below the median household income peak at 52,623 U.S. dollars that occurred in 1999.
The median household income depicts the income of households, including the income of the householder and all other individuals aged 15 years or over living in the household. This measure also includes single person households and gives a skewed perspective on the average income. Family income provides better data. Income includes wages and salaries, unemployment insurance, disability payments, child support payments received, regular rental receipts, as well as any personal business, investment, or other kinds of income received routinely.
The median household income in the United States varies from state to state. In 2014, the median household income was about 76,165 U.S. dollars in Maryland, while the median household income in Mississippi was approximately 35,521 U.S. dollars at that time.
Household income is also used to determine the poverty line in the United States. In 2015, about 13.5 percent of the U.S. population was living in poverty. The child poverty rate, which represents people under the age of 18 living in poverty, has been growing steadily over the last decade, from 16.2 percent of the children living below the poverty line in year 2000 to 20 percent in 2013.
Income inequality has grown significantly in the United States. Studies about the income gap between the poor and the rich in the United States in year 2012, show that 65 percent of the Americans consider the income gap between the rich and the poor has gotten larger.
The state with the widest gap between the rich and the poor was New York, with a gini coefficient score of 0.51 in 2014. The Gini coefficient is calculated by looking at average income rates. A score of zero would reflect perfect income equality and a score of 1 indicates a society where one person would have all the money and all other people have nothing. The state with the smallest Gini coefficient was Alaska with 0.42.
