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: 
During regular data collection and processing checks, errors were identified in the NSDUH data. These errors affected the data for Pennsylvania (2006-2010) and Maryland (2008-2009). These errors had minimal impact on the national estimates and no effect on direct estimates for the other 48 states and the District of Columbia. Comparing estimates for Pennsylvania, Maryland, the mid-Atlantic division, and the Northeast region were of most concern. As a result in 2013, the original baseline was revised from 94.4 to 86.9 percent. The target was adjusted from 96.4 to 88.9 percent to reflect the revised baseline using the original target-setting method. In 2014, the baseline data was revised from 86.9 to 94.3 percent due to a programming error for the original estimate. The target was adjusted from 88.9 to 96.3 percent to reflect the revised baseline using the original target-setting method.
