Introduction
Insights into the prevalence rate of ADHD in the U.S. and in New York, New Jersey, Pennsylvania, Connecticut, Massachusetts, and Maryland from 2012 to 2021, where available, have been provided in the ADD/ADHD tab of the attached spreadsheet. Where data wasn't available, we have entered 'NA' in the spreadsheet. Additional details on the research methodology is available in the strategy section below.
Findings
- ADHD prevalence is generally measured for children (2-17 years).
- The national prevalence of ADHD in the US between 1997 and 2018 is detailed in the table below:
- The ADHD rate in 2019 and 2020 are presented in the table below:
- State-level ADD/ADHD data for New York, New Jersey, Pennsylvania, Connecticut, Massachusetts, and Maryland for 2016 to 2019 and 2019-2020 (two years combined) have been provided in the spreadsheet.
- State-level data between 2012 and 2015 is unavailable.
- Data for 2021 has not yet been published.
Research Strategy
To provide data on the ADHD prevalence rate in the US and in New York, New Jersey, Pennsylvania, Connecticut, Massachusetts, and Maryland from 2012 to 2021, our research team extensively searched government databases, peer-review journal databases, health industry databases, statistical databases, and media reports such as the CDC, U.S. Census Bureau, the Health Resources and Services Administration (HRSA), National Survey of Children’s Health, Jama Network, National Health Interview Survey (NHIS), Children and Adults with Attention-Deficit/Hyperactivity Disorder (CHADD), among others. After an extensive search, we discovered that data on ADHD rates is typically provided for children nationally by the Department of Health and Human Services and Maternal and Child Health Bureau (MCHB) of the Health Resources and Services Administration (HRSA). We were able to find national data between 2012 and 2020 only. Data for 2021 is generally not available currently as the report hasn't been published. For state-level data, however, we were only able to find data between 2016 and 2019 as well as for 2019 and 2020 combined as earlier reports did not provide state-level data. Hence, we have entered "NA" where data is unavailable.
