Comparable Healthy People 2010 Objective: 
Not applicable
Data Collection Frequency: 
Periodic
Methodology Notes: 

    The baseline (2006) and subsequent data points for this sub-objective have been revised to measure the proportion of children with ASD having a first evaluation by 36 months among non-migrant children. The term “non-migrant” is defined as children who were born in the ADDM surveillance state and resided in the respective surveillance area at the time of ascertainment (age 8 years), determined by birth certificate linkage. This population is expected to have better availability of early records due to a greater likelihood of residing in the surveillance area prior to 36 months of age. Both the numerator and denominator for this sub-objective are restricted to the non-migrant population of children with ASD. Reporting this proportion restricted to non-migrant children is consistent with the ADDM Network 2010 prevalence report.

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 39.0 to 42.7 (2006) percent due to a change in the methodology. The target was adjusted from 42.9 to 47.0 percent using the original target setting method. Also the the words “an” and “with” were removed from the objective text and the word “having” was added to reflect how the term ASD currently used.
