Data Source

The data used for this measure come from the Washington State Healthy Youth Survey (HYS). Data can be found at:

S: Data have been suppressed due to low response rates (below 40% participation).

*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.

At this time HYS does not recommend that you attempt to determine significant trends over time, only to determine changes from a single survey administration to another, i.e., a change from 2006 to 2008. For trend analysis, we recommend that you have at least 5 data points.

The Healthy Youth Survey is based on a random sample of 6th, 8th, 10th and 12th graders in schools across Washington State. The HYS is a collaborative effort of the Office of the Superintendent of Public Instruction, the Department of Health, the Department of Social and Health Service's Division of Alcohol and Substance Abuse, Community Trade and Economic Development, the Family Policy Council and the Liquor Control Board.
