      Quick Statistics About Voice, Speech, Language


Voice, Speech, Language, and SwallowingNearly 1 in 12 (7.7%) U.S. children ages 3-17 has had a disorder related to voice, speech, language, or swallowing in the past 12 months.1Among children who have a voice, speech, language, or swallowing disorder, 34% of those ages 3-10 have multiple communication or swallowing disorders, while 25.4% of those ages 11-17 have multiple disorders.1Boys ages 3-17 are more likely than girls to have a voice, speech, language, or swallowing disorder (9.6% compared to 5.7%).1The prevalence of voice, speech, language, or swallowing disorders is highest among children ages 3-6 (11.0%), compared to children ages 7-10 (9.3%), and children ages 11-17 (4.9%).1Nearly 1 in 10, or 9.6%, of Black children (ages 3-17) has a voice, speech, language, or swallowing disorder, compared to 7.8% of White children and 6.9% of Hispanic children.1More than half (55.2%) of U.S. children ages 3-17 with a voice, speech, language, or swallowing disorder received intervention services in the past year.1 White children (ages 3-17) with a voice, speech, language, or swallowing disorder are more likely to have received intervention services in the past 12 months, compared to Hispanic and Black children, at 60.1%, 47.3%, and 45.8% respectively.1Boys (ages 3-17) with a voice, speech, language, or swallowing disorder are more likely than girls to receive intervention services, at 59.4% and 47.8%, respectively.1Among children ages 3-17 who have a voice, speech, language, or swallowing disorder, those with speech or language problems, 67.6% and 66.8% respectively, are more likely to receive intervention services, compared to those who have a voice disorder (22.8%) or swallowing problems (12.7%).1VoiceAn estimated 17.9 million U.S. adults ages 18 or older, or 7.6%, report having had a problem with their voice in the past 12 months.3,4 Approximately 9.4 million (4.0%) adults report having a problem using their voice that lasted 1 week or longer during the last 12 months.21.4% of U.S. children have a voice disorder that lasted for a week or longer during the past 12 months.1Spasmodic dysphonia, a voice disorder caused by involuntary movements of one or more muscles of the larynx (voice box), can affect anyone. The first signs of this disorder are found most often in people ages 30-50. More women than men appear to be affected.5Speech5% of U.S. children ages 3-17 have a speech disorder that lasted for a week or longer during the past 12 months.1The prevalence of speech sound disorders (namely, articulation disorders or phonological disorders) in young children is 8 to 9%. By the first grade, roughly 5% of children have noticeable speech disorders, including stuttering, speech sound disorders, and dysarthria; the majority of these speech disorders have no known cause.6,7More than 3 million Americans (about 1%) stutter. Stuttering can affect individuals of all ages but occurs most frequently in young children between the ages of 2 and 6. Boys are two to three times more likely than girls to stutter. Although most children who stutter outgrow the condition while young, as many as 1 in 4 will continue to stutter for the rest of their lives, a condition known as persistent developmental stuttering.8,9LanguageDevelopmental language disorder (also called specific language impairment) has a prevalence of 7% or approximately 1 in 14 children.10,11Approximately 2% of children with a language disorder also have an existing medical condition (e.g., autism, intellectual disability).113.3% of U.S. children ages 3-17 have a language disorder that lasted for a week or longer during the past 12 months.1Research suggests that the first 6 months of life are the most crucial to a child’s development of language skills. For a person to become fully competent in any language, exposure must begin as early as possible, preferably before school age.12,13Anyone can acquire aphasia (a loss of the ability to use or understand language), but most people who have aphasia are in their middle to late years. Men and women are equally affected. Nearly 180,000 Americans acquire the disorder each year.14 About 2 million people in the United States currently have aphasia.14Swallowing0.9% of U.S. children ages 3-17 have a swallowing disorder that lasted for a week or longer during the past 12 months.1SourcesBlack, LI; Vahratian, A; Hoffman, HJ (2015): Communication disorders and use of intervention services among children aged 3–17 years: United States, 2012. *NCHS data brief*.
