Definitions: The number and share of children who live in families with income below the poverty threshold (100% Federal Poverty Guideline) as defined by the U.S. Office of Management and Budget. These figures are divided into seven age groups: under 5 years, 5 years, 6 to 11 years, 12 to 14 years, 15 years, 16 and 17 years, and total under 18 years.

Data Source: The U.S. Census Bureau's American Fact Finder, 2005-2009, 2006-2010, 2007-2011, 2008-2012, 2009-2013, 2010-2014, and 2011-2015 American Community Survey (ACS) 5-Year Estimates. Data were retrieved on June 29, 2017 from: (Table B17001).

*Please use these estimates with caution. The total confidence interval (upper bound minus lower bound) of the percent estimate, 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.

S: These data have been suppressed because the percent estimates have a total confidence interval of 10 percentage points or greater and/or the counts are 10 or fewer.

The 2011-2015 ACS data release marked the seventh time that 5-year estimates were released for all counties in Washington state. 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 ACS estimates. However, these estimates are more reliable than 1-year and 3-year ACS estimates because they are based on a larger sample size. The 5-year estimates are also available for all geographic areas because of their sample size, whereas the 3-year  estimates are published for populations of 20,000 or greater, and the 1-year estimates are only published for populations of 65,000 or greater. More information about 1-year versus 3-year versus 5-year ACS surveys and estimates are available online at

The federal poverty definition consists of a series of thresholds based on family size and composition. In 2014, the Census poverty threshold for a family of two adults and two children was $24,008.
