Abstract The United States Bureau of Labor Statistics and other sources were consulted about the percentages of the working population that we identified as professional voice users. The largest percentage may be in sales and sales-related occupations (13\%), but the exact breakdown of those who approach their clients vocally rather than by mail is still uncertain. The second largest population is teachers, who comprise 4.2\% percent of the U.S. workforce (1994 statistic). Teachers have been identified as having the greatest incidence of voice disorders. Population data are also given for professional voice users who could present a significant hazard to public safety if their vocal communication skills were severely impaired.
