Redefining the Survival of the Fittest: Communication Disorders in the 21st Century

TLDR

The study aims to quantify the economic impact of caring for and losing employment opportunities among people with communication disorders in the United States. The authors surveyed historical and contemporary governmental and scholarly data on workforce distribution and epidemiology of hearing, voice, speech, and language disorders, and analyzed these data for industrialized countries, North America, and the United States. The analysis estimates that communication disorders affect 5–10 % of the population, cost the US $154–186 billion annually (2.5–3 % of GDP), and disproportionately disadvantage those with severe speech disabilities, thereby reducing economic output and posing a growing public‑health challenge.

Abstract

Abstract Objectives: To determine the economic effect on the US economy of the cost of caring for people with communication disorders as well as the cost of lost or degraded employment opportunities for people with such disorders, including disorders of hearing, voice, speech, and language. Study Design: Survey of available historical and contemporary governmental and scholarly data concerning work force distribution and the epidemiology of disorders of hearing, voice, speech, and language. Method: Analysis of epidemiological and economic data for industrialized countries, North America, and the United States. Results: Communication disorders are estimated to have a prevalence of 5% to 10%. People with communication disorders may be more economically disadvantaged than those with less severe disabilities. The data suggest that people with severe speech disabilities are more often found to be unemployed or in a lower economic class than people with hearing loss or other disabilities. Communication disorders may cost the United States from $154 billion to $186 billion per year, which is equal to 2.5% to 3% of the Gross National Product. Conclusions: Communication disorders reduce the economic output of the United States, whose economy has become dependent on communication‐based employment. This trend will increase during the next century. The economic cost and the prevalence rates of communication disorders in the United States indicate that they will be a major public health challenge for the 21st century.
