18 Million People in the UK Are Deaf or Have a Hearing Loss

Contents

Introduction

For years, the commonly quoted figure for the number of people in the UK who are Deaf or have hearing loss has been 12 million. But that number has now significantly increased, not because hearing loss has suddenly grown overnight, but because the way we understand and measure it has evolved.

Updated research shared by RNID reports that the true number is closer to 18 million people. This shift in data brings important clarity, better reflects lived experiences, and highlights just how many individuals are navigating the world with some degree of hearing loss.

Understanding this change matters for businesses, employers, and society as a whole. It reshapes the scale of need, strengthens the case for accessibility, and reinforces why Deaf inclusion can no longer be seen as optional.

Here’s what sits behind the new figure, and why it requires a wider conversation about communication, accessibility, and inclusion.

Why the Number Has Increased

RNID’s updated statistic is grounded in new academic analysis from two leading hearing science experts: Professor Michael Akeroyd (University of Nottingham) and Professor Kevin Munro (University of Manchester). Their research, published in the International Journal of Audiology, re-evaluates how hearing loss prevalence is calculated in the UK.

The increase from 12 million to 18 million does not represent a sudden rise in hearing loss. Instead, it results from three key changes:

  • Updated population data: The new calculation uses figures from the 2021–22 census, replacing the previous estimates based on the 2011 census.
  • Inclusion of lower-level hearing loss: People with milder forms of hearing loss are now included, capturing experiences that were previously overlooked.
  • Recognition of one-sided hearing loss: Individuals with hearing loss in one ear, who were not counted before, are now part of the total.

Together, these changes provide a more accurate and inclusive picture of the UK’s hearing landscape, acknowledging the full spectrum of hearing loss that affects everyday communication.nd language, particularly when it comes to unfamiliar or formal terminology.

Reflecting Real Lived Experience

RNID has welcomed the recalculation, emphasising that this updated figure better represents the real experiences of millions of people. Hearing loss is not a single, uniform condition, it spans a wide range of needs, challenges, and communication preferences.

Professor Kevin Munro explains that the new data “more accurately reflect the number of adults in the UK who have hearing loss that will cause listening difficulty, especially in background noise,” adding that maintaining hearing health is a “strong social responsibility.”

This broader and more accurate understanding brings validation to people whose experiences were previously underrepresented. It also sheds light on how common hearing loss truly is, reinforcing that accessibility should be built in from the start, not added later as a special adjustment.

What This Means for Businesses

With 18 million people in the UK now recognised as Deaf or having hearing loss, the case for accessible communication is stronger than ever.

For businesses, this is not just a statistic, it is a call to action.

A population this large represents a major customer group, a significant proportion of the workforce, and a community whose needs must be recognised and responded to. It highlights why captions, clear communication channels, BSL access, visual alerts, and inclusive service design are essential in modern customer and employee experiences.

The updated figure also underscores the economic significance of the Purple Pound, demonstrating the scale of opportunity available to organisations that take Deaf inclusion seriously.

Final Thoughts

The shift from 12 million to 18 million people with hearing loss in the UK is more than a change in data, it’s a shift in understanding. By recognising every degree of hearing loss, we get a fuller, more honest picture of how many people rely on accessible communication and inclusive environments.

This recalibration brings visibility to millions of individuals who were previously uncounted. It reminds businesses, employers, and policymakers that Deaf inclusion is not a niche topic, it affects a substantial part of society.

As organisations look ahead, this new figure strengthens the case for designing services, workplaces, and customer experiences that work for everyone. The more accurately we understand the communities we serve, the more effectively we can create environments where people feel heard, valued, and included.
