Definitions: Median annual income for families with own children under age 18 living in the household.
"Own children" include the householder's (head of the household) children by birth, marriage, or adoption.The median income is the dollar amount that divides the income distribution into two equal groups--half with income above the median, half with income below it.
Income data are collected for the 12 months prior to the survey and are adjusted to reflect income in December of the survey year. For example, respondents who received the survey in January 2005 reported income for January through December 2004. Respondents who received the survey in December 2005 reported income for December 2004 through November 2005. All of that income data was weighted to reflect December 2005 dollars.

Data Source: Population Reference Bureau, analysis of data from the U.S. Census Bureau, 2005 through 2011 American Community Survey.
The data for this measure come from the 2005 through 2011 American Community Survey (ACS). Beginning in January 2005, the U.S. Census Bureau expanded the ACS sample to 3 million households (full implementation), and in January 2006 the ACS included group quarters. The ACS, fully implemented, is designed to provide annually updated social, economic, and housing data for states and communities. (Such local-area data have traditionally been collected once every ten years in the long form of the decennial census.)

Note: The District of Columbia, Puerto Rico and the U.S. Virgin Islands are
not included in maps and rankings because they are not states and therefore comparisons on many
indicators of child well being are not meaningful.
