Definitions: The number and share of grandparents responsible for their own grandchildren under 18 years of age who have incomes below the poverty threshold (100% Federal Poverty Guideline) as defined by the U.S. Office of Management and Budget.

Data Source: The U.S. Census Bureau's American Fact Finder, 2005-2007, 2006-2008, 2007-2009, and 2008-2010 American Community Survey (ACS) 3-Year Estimates. Data were retrieved from: http://factfinder2.census.gov  (Table B10059).

*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.

The 2008-2010 ACS data release marked the third time that 3-year estimates were released for areas with populations of 20,000 and greater. The ACS 2008-2010 data were collected during calendar years 2008, 2009, and 2010.

The 3-year ACS estimates represent the average characteristics over the 3-year period of time, and therefore are less current than 1-year ACS estimates. However, these estimates are more reliable because they are based on a larger sample size. The 3-year estimates are also available for more geographic areas because they are published for 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 versus 3-year ACS surveys and estimates are available online at http://www.census.gov/acs/www/data_documentation/documentation_main/.

The federal poverty definition consists of a series of thresholds based on family size and composition. In 2009, the poverty threshold for a family of two adults and two children was $22,113.
