How ADHD Compares

Annual U.S. economic cost vs. other major conditions

Diabetes $412.9B[18]
Major Depression $326B[19]
ADHD $143B to $266B[1]
Heart Disease $216B[20]
The funding gap: Despite comparable economic burden, ADHD receives a fraction of NIH research funding compared to conditions with similar or lower costs. NIH categorical spending data is available at report.nih.gov.

The annual cost per individual with ADHD

Excess annual societal cost per adult $14,092
Annual income gap vs. non-ADHD peers $8,900 to $15,400

$14,092: Schein et al. (2022)[2] | Income gap: Biederman & Faraone (2006)[4]

Projected Lifetime Earnings Loss[5]
Males, combined-type ADHD, full career projection $1.27M
All participants, projected from age 25 $543K

From the Pittsburgh ADHD Longitudinal Study (Pelham et al., 2016 & 2020). These are projections based on earnings at age 25 to 30, assuming the gap persists over a full career. Actual outcomes vary with treatment, career path, and severity.

Comparative Impact
Lost role performance days per year 22.1 days
vs. ~4 days for non-ADHD workers[3]
Fired from at least one job 60% more likely

Impulse buying score +57%

Full-time employment rate 34%
vs. 59% for non-ADHD adults[4]

Comorbidity Rates
At least one comorbid condition ~78%
Anxiety disorders 25 to 50%
Depression 19 to 53%

Racial & Ethnic Disparities

ADHD diagnosis rates by race/ethnicity, children ages 5 to 17

White, non-Hispanic 13.4%
Black, non-Hispanic 10.8%
Hispanic 8.9%

Source: NCHS Data Brief No. 499, NHIS 2020 to 2022[12]. Asian non-Hispanic children have the lowest diagnosis rates but are not separately reported in this data brief.

The gap is narrowing: Between 2004 to 2016, diagnosis rates among Black children grew at 3× the rate of White children, suggesting historic underdiagnosis is being corrected.
Treatment disparity: Hispanic, Black, and other minority children with ADHD are significantly less likely to receive medication than White children, even after diagnosis.

The 2.7× gap: A child in Louisiana is 2.7× more likely to receive an ADHD diagnosis than a child in California. This likely reflects differences in diagnostic culture, insurance coverage, and provider availability, not biology. Notably, several states with the highest diagnosis rates also have among the fewest mental health providers per capita.
