Disability Data Trends: Understanding Our Shared Future

This chapter helps you understand how common disability is across the globe, and why accessibility is a universal need, not a niche one. You’ll explore global disability statistics, learn why prevalence data varies by region and methodology, and build the context needed to interpret accessibility requirements with confidence. This foundation supports key CPACC exam concepts while reinforcing why accessible design matters in real-world practice.

As people age, the likelihood of experiencing a disability increases significantly. From a statistical standpoint, most individuals will encounter some form of disability during their lifetime, whether temporary or permanent. Disability is not limited to a small or separate group; it affects individuals, families, and communities across generations. Understanding this reality is essential when examining the broader, global impact of disability.

Below, we’ll examine global data surrounding disability, helping you see the scale of accessibility needs worldwide and giving you the insight needed to apply inclusive practices confidently, key skills for CPACC certification.

Understanding the Data: Why Numbers Vary

Before we explore statistics, an important note: statistical data on disability are collected and categorized in many different ways, so it's crucial to understand the context of each study.

There are general limitations in collecting disability statistics, including:

  • Census surveys often do not capture detailed information about different types of disabilities.

  • Disability terminology and definitions vary across countries, making direct comparisons challenging.

  • Many individuals experience multiple disabilities and may not fit neatly into predefined categories.

Keep these factors in mind when analyzing and communicating statistics on disability. Despite these limitations, these statistics can provide valuable context for understanding the scale of accessibility challenges or informing effective interventions.

Think about why standard categories might not capture everyone's experiences with disability accurately.

The Big Picture

According to the World Health Organization, 1 in 6 people worldwide live with a disability. That’s roughly 1.3 billion people (or 16% of the world’s population).

To put that number into perspective: if people with disabilities were considered a single nation, it would be the world’s most populous country, surpassing even China or India. Yet this “nation” faces systemic barriers, including reduced life expectancy, poorer health outcomes, and limited access to fundamental rights such as education and employment.

The Aging Connection

Disability is not something that only affects “other people.” Nearly half of individuals over the age of 60 experience some form of disability. For many, aging itself introduces challenges such as mobility limitations, changes in vision or cognition, and the need for assistance with daily activities. This underscores why accessibility benefits everyone, not just those with permanent or early-onset disabilities.

Consider your oldest living relative: what accessibility features do they rely on? Glasses, ramps, or larger text on a smartphone are all examples of accommodations that support independent participation.

Disability Statistics Worldwide

Now that we've established the global baseline, let's examine how disability prevalence varies across regions, revealing both universal patterns and the critical importance of understanding context when interpreting accessibility data.

United States and Canada

  • Map of United States of America (U.S.A)

    United States of America

    28.7% of the population has some form of disability

  • Map of Canada

    Canada

    27% of the Canadian Population aged 15 and older had one or more disabilities that limited their daily activities

In the United States, the CDC reports that 28.7% of the population has some form of disability, based on a broad functional definition that encompasses mobility, cognition, vision, hearing, and challenges related to independent living. 

In contrast, data from the US Census 2024 shows that about 44.1 million Americans with disabilities make up 13% of the civilian noninstitutionalized population. This narrower definition excludes individuals in institutional settings and uses a limited set of disability indicators, resulting in a lower reported percentage.

These differences highlight an important concept for accessibility professionals: the prevalence of disability varies depending on the definitions, survey methods, and populations included. No single statistic tells the full story, but together they demonstrate the scale of disability in the U.S.

Canada shows a similar pattern. According to the Canadian Survey on Disability(opens in a new tab), 27% of Canadians aged 15 and older (8.0 million people) had one or more disabilities that limited them in their daily activities.

Across both countries, the data reinforces a key takeaway: disability is not a niche experience. More than one in four people are affected, underscoring the importance of accessibility as a core requirement rather than an afterthought.

European Union and the United Kingdom

  • Map of Europe

    European Union

    24% of the EU population aged 16 and older was reported to have some form of disability

  • Map of UK and North Ireland

    United Kingdom

    16.8 million people were disabled in 2023-2024, representing 25% of the total population

Disability prevalence across the European Union and the United Kingdom is similar to trends in North America, reinforcing that disability is a widespread and consistent part of the global population. 

In the United Kingdom, the most recent Department for Work and Pensions (DWP) Family Resources Survey estimates that 16.8 million people were disabled in 2023-2024(opens in a new tab), representing 25% of the total population. Among working-age adults, 10.21 million people, roughly 24%, are disabled, highlighting the significant intersection between disability, employment, and economic participation. 

Across the European Union, the pattern is strikingly similar. In 2024, 24% of the EU population(opens in a new tab) aged 16 and older was reported to have some form of disability. According to Eurostat, this equates to 107 million people.

Central and South America

  • Map of Mexico

    Mexico

    Mexico reports a disability prevalence of 5.39%

  • Map of Brazil

    Brazil

    Brazil reports a disability prevalence of 24.9%

Disability prevalence across Central and South America varies widely, primarily due to differences in how countries define, measure, and report disability. The table below highlights the reported prevalence of disability across select countries in South and Central America. These figures should be interpreted as estimates rather than direct comparisons, offering insight into regional trends rather than definitive rankings.

Africa

  • Map of Africa

    Africa

    Official statistics in some African nations report low percentages (2-5%), estimates from the WHO suggest that the actual figures could be as high as 15% in certain regions

Disability prevalence varies significantly by country. However, reliable data are challenging to obtain due to inconsistencies in data collection. While official statistics in some African nations report low percentages (2-5%), estimates from the WHO suggest that the actual figures could be as high as 15% in certain regions, influenced by factors such as conflict, poverty, and limited access to healthcare.

Specific country examples show varied prevalence rates:

  • A 2025 study reported prevalence from 0.7% in Nigeria to 10.9% in the Central African Republic

  • Other studies show rates from 1.7% in Mali to 17.1% in Sierra Leone

The wide range likely reflects differences in how disability is defined and measured rather than actual prevalence differences.

  • Map of China

    China

    85 million people (6.2% of the population) were reported to have some form of disability as of 2018

  • Map of Japan

    Japan

    7.6% of the population of Japan (or about 9.63 million people) live with physical, intellectual, or mental disabilities

In India, the 2011 and 76th rounds of the National Sample Survey estimated disability prevalence at 2.2%(opens in a new tab), notably lower than the global average. This lower figure may reflect differences in survey methods and data collection rather than actual prevalence. 

In China, approximately 85 million people (6.2% of the population(opens in a new tab)) were reported to have some form of disability as of 2018, with a disproportionate number living in rural areas (75%). The prevalence varies by type of disability, with mobility and hearing impairments among the most commonly cited. 

In Japan, around 7.6% of the population (PDF)(opens in a new tab) (or about 9.63 million people) live with physical, intellectual, or mental disabilities. Disability prevalence is higher among older adults, and functional disability remains a significant social and medical concern. 

Across Asia, these figures illustrate a wide variation in reported disability prevalence, which stems from differences in survey methods, definitions, and the populations included. Taken together, they highlight the widespread nature of disability and underscore the importance of considering data context when using prevalence statistics in accessibility planning and policy. 

Southeast Asia

In Southeast Asia, an estimated 15% of the population(opens in a new tab) lives with a disability. Nearly 90 million people.

Major contributing factors include:

  • High prevalence of non-communicable diseases like cardiovascular diseases (a leading cause of death)

  • Injuries such as road traffic accidents, which contribute significantly to disability

  • Minimal access to assistive technology in many parts of the region

Australia and New Zealand
