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 94.9 to 94.8 percent. However, the 100 percent target was retained.
