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 2014, the original baseline was revised from 18.4 percent (2009) to 28.7 percent (2011) due to changes in the sequence of the survey questions. In 2009, the question used to track this objective was located in the middle of the physical activity section of the questionnaire; for 2011, it was moved to the beginning of the physical activity questionnaire and the change in placement affected the survey responses. The target was adjusted from 20.2 to 31.6 percent to reflect the revised baseline using the original target-setting method.
