The median family income is based on the annual income of all members within the family. The median income is the dollar amount at which half of all families in the area have more income and half have less, by presence of own children under 18. The state-level and county-level figures reported here are 5-year estimates.
Data for this measure come from the U.S. Census Bureau's American Fact Finder, American Community Survey (ACS) 5-Year Estimates.
Data were retrieved on June 29, 2017 from from http://factfinder2.census.gov (Table B19125).
*Please use these estimates with caution. The relative size of the margin of error is 10 percentage points or greater, which indicates that this estimate has a large margin of error. This generally occurs when estimate relies on small number of cases. To obtain total confidence interval values around the estimates for this indicator please contact Washington KIDS COUNT.

The U.S. Census Bureau often revises previous estimates. Therefore, figures presented here may be different from figures presented elsewhere.
A family includes a householder and one or more people living in the same household who are related to the householder by birth, marriage, or adoption. All people in a household who are related to the householder are regarded as members of his or her family. According to the ACS subject definitions guide ( http://www.census.gov/acs/www/UseData/Def.htm) a household contains only one family in the published tabulations.
The 2011-2015 ACS data release marked the seventh time that 5-year estimates were released for all areas. The ACS 2011-2015 data were collected during calendar years 2011, 2012, 2013, 2014, and 2015.
The 5-year ACS estimates represent the average characteristics over the 5-year period of time, and therefore are less current than 1-year and 3-yearACS estimates. However, these estimates are more reliable because they are based on a larger sample size and provide data for counties with populations less than 20,000. The 3-year estimates are available for geographic areas with populations of 20,000 or greater, while 1-year estimates are only published for populations of 65,000 or greater. More information about 1-year, 3-year, and 5-year ACS surveys and estimates are available online at http://www.census.gov/acs/www/guidance_for_data_users/guidance_main/.
