Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
In 2012, the original baseline was revised from 42.0 to 39.6 percent due to changes in how the response “don’t know” is handled. Previously responses of “don’t know” were excluded, but they are now included as lack of awareness. The target was proportionally adjusted from 46.2 percent to 43.6 percent to reflect the revised baseline using the original target-setting method.
