Neurodiversity in the workplace: key statistics for 2026
How many people are neurodivergent?
The most widely cited estimate is that 15-20% of the population is neurodivergent, roughly one in five people. The term covers a range of cognitive profiles, including ADHD, autism, dyslexia, dyspraxia, dyscalculia and Tourette syndrome, among others. Deloitte uses the same framing in its workplace research, noting that around one in five adults are neurodivergent and describing this group as one of the largest pools of untapped talent available to employers.
Prevalence varies by condition. Dyslexia is generally estimated to affect somewhere between 5% and 20% of people depending on how it is measured; ADHD affects an estimated 3-4% of adults; and autism is diagnosed in a smaller but growing share of the population. Two things make the true figure hard to pin down: many adults were never assessed as children, and awareness has risen sharply, so identification rates are still climbing. In practical terms for a manager, the takeaway is simple, on any team of ten or more people, it is likely that at least one or two think, focus or process information differently from the "neurotypical" majority, whether or not they have ever said so.
The employment gap: talent left on the table
Neurodivergent people are well represented in the population but badly under-represented in stable employment. In the United Kingdom, which publishes some of the most detailed data available, the Office for National Statistics reports that only around 3 in 10 autistic adults are in work, the lowest employment rate of any disability group. Estimates for broader neurodivergent unemployment and underemployment run far higher than the general population in study after study, though the exact figures vary widely with how each survey defines its terms.
The Canadian picture points the same way. According to Statistics Canada's 2022 Canadian Survey on Disability, 62% of working-age adults (25-64) with disabilities were employed, compared with 78% of those without, a 16-percentage-point gap, and many neurodivergent people are included in that disability figure. The most revealing detail is what happens with education: among people with a bachelor's degree or higher, that gap narrows to just a few points. When access and opportunity are present, the difference nearly disappears, a strong signal that the barrier is workplace design and hiring processes, not capability.
The business case: what the performance data shows
The flip side of the employment gap is a measurable performance opportunity. Deloitte's analysis found that teams which include neurodivergent professionals can be up to 30% more productive than those that don't, and that inclusive organizations are markedly more likely to be innovative and agile. Structured hiring programs back this up: Deloitte reports that established neurodivergent recruitment initiatives at companies such as SAP and Microsoft sustain retention rates above 90%, well above typical industry averages.
Individual programs report striking results too. JPMorgan Chase has said participants in its Autism at Work initiative became faster and more accurate than peers in comparable roles once given the right environment and support. Figures from a single employer should be read as illustrative rather than universal, but the direction is consistent across sources: when neurodivergent employees are matched to suitable work and supported by capable managers, quality, speed and loyalty tend to rise. The gains are not automatic, though. They depend on the management around the talent, which is where the next set of numbers becomes important.
The manager gap: why the numbers don't improve on their own
If the talent and the performance upside are both real, why does the employment gap persist? The clearest answer in the data is a capability gap among managers. The CIPD, the professional body for HR and people management, surveyed employers for its 2024 Neuroinclusion at Work report and found that fewer than half of managers (46%) feel confident and capable of supporting neurodivergent staff, and only around half (51%) felt they fully appreciated the value of a neuro-inclusive organization.
That uncertainty has a knock-on effect on disclosure. The same body of research found that roughly 31% of neurodivergent employees had not told their line manager or HR about their neurodivergence, often citing privacy, stigma or worry about career impact. Deloitte likewise reports that nearly one in three neurodivergent employees have experienced discrimination or bias related to their neurodivergence, and some 2024 surveys found as many as one in three neurodivergent workers worried about losing their job because of it. When people don't feel safe to be open, managers can't offer the small, practical adjustments that unlock performance, so the potential quietly goes unrealized on both sides.
What these statistics mean for your organization
Read together, the numbers tell a coherent story. A large share of your workforce is neurodivergent whether or not anyone has disclosed it. The performance upside of supporting them well is significant and documented. And the single biggest lever is not a policy or a perk. It is manager confidence and everyday skill, which most organizations have not yet built. That is encouraging, because manager capability is one of the most trainable things an organization can invest in.
A sensible starting point is to find out where your own managers stand rather than assuming. You can benchmark that in a couple of minutes with the free Manager Scorecard, then close the specific gaps with short, practical training and a toolkit managers can use the same week.

FAQ
How many people are neurodivergent?
Researchers estimate that 15-20% of people, roughly 1 in 5, are neurodivergent, a group that includes people with ADHD, autism, dyslexia, dyspraxia and other cognitive profiles. Because many adults are never formally identified, the true figure may be higher.
Are neurodiverse teams really more productive?
Research from Deloitte indicates that teams which include neurodivergent professionals can be up to 30% more productive than those that don't, and structured hiring programs at companies such as SAP and Microsoft report retention rates above 90%. The gains come from pairing different thinking styles with management that plays to people's strengths.
What share of managers feel confident supporting neurodivergent staff?
According to the CIPD's 2024 Neuroinclusion at Work report, fewer than half of managers (46%) feel confident and capable of supporting neurodivergent colleagues, and about 31% of neurodivergent employees have not told their manager or HR about their neurodivergence. Building manager capability is the fastest way to close that gap.
Are these neurodiversity statistics specific to Canada?
Some are. Statistics Canada's 2022 Canadian Survey on Disability reports a 16-point employment gap between working-age adults with and without disabilities (62% versus 78%). Because neurodiversity-specific labour data is still limited in North America, this article also draws on robust international research from Deloitte, the CIPD and the UK Office for National Statistics.
