Around 2020, over 1.5 billion people worldwide lived with hearing loss of some degree, and the expected rise to 2.5 billion by 2050 is already reshaping public health priorities. What’s striking is how many causes sit behind it, from chronic ear infections and noise exposure to diabetes, cardiovascular disease, genetics, and certain medications. This post pulls together the key hearing loss statistics that quantify those risks and outcomes, including what could be prevented or addressed earlier.
