About 2 to 3 out of every 1,000 children in the United States are born with a detectable level of hearing loss in one or both ears. (1) More than 90 percent of deaf children are born to hearing parents. (1)
Approximately 15% of American adults (37.5 million) aged 18 and over report some trouble hearing. (1)
Men are more likely than women to report having hearing loss. (2)
One in eight people in the United States (13 percent, or 30 million) aged 12 years or older has hearing loss in both ears, based on standard hearing examinations. (3)
About 2 percent of adults aged 45 to 54 have disabling hearing loss. The rate increases to 8.5 percent for adults aged 55 to 64. Nearly 25 percent of those aged 65 to 74 and 50 percent of those who are 75 and older have disabling hearing loss. (4)
The NIDCD estimates that approximately 15 percent of Americans (26 million people) between the ages of 20 and 69 have high frequency hearing loss due to exposure to noise at work or during leisure activities.(5)
Roughly 10 percent of the U.S. adult population, or about 25 million Americans, has experienced tinnitus lasting at least five minutes in the past year. (6)
Among adults aged 70 and older with hearing loss who could benefit from hearing aids, fewer than one in three (30 percent) has ever used them. Even fewer adults aged 20 to 69 (approximately 16 percent) who could benefit from wearing hearing aids have ever used them. (7)
As of December 2012, approximately 324,200 cochlear implants have been implanted worldwide. In the United States, roughly 58,000 devices have been implanted in adults and 38,000 in children.(8)
Five out of 6 children experience ear infection (otitis media) by the time they are 3 years old.(9)
Severe to profound hearing loss is expected to cost society $297,000 over the lifetime of an individual. (10)
Most of these losses (67%) are due to reduced work productivity, although the use of special education resources among children contributes an additional 21%. Life time costs for those with prelingual onset exceed $1 million. (11)
Genes are responsible for hearing loss among 50% to 60% of children with hearing loss. About 20% of babies with genetic hearing loss have a “syndrome” (for example, Down syndrome or Usher syndrome). (12)
Infections during pregnancy in the mother, other environmental causes, and complications after birth are responsible for hearing loss among almost 30% of babies with hearing loss. (13)
Congenital cytomegalovirus (CMV) infection during pregnancy is a preventable risk factor for hearing loss among children. (14)
14% of those exposed to CMV during pregnancy develop sensorineural hearing loss (SNHL) of some type. About 3% to 5% of those exposed to CMV during pregnancy develop bilateral moderate-to-profound SNHL. A 2005 HealthStyles survey by CDC found that only 14% of female respondents had heard of CMV. About one in every four children with hearing loss also is born weighing less than 2,500 grams (about 5 1/2 pounds). (15)
Nearly one-quarter of children with hearing loss has one or more other developmental disabilities, such as cerebral palsy, intellectual disability, or vision loss. (16)

Communication & Education
Entry rates into college for students with hearing loss are close in parity with other students, the drop out rate is 71% vs. 41% for other students, and this disparity is thought to be due largely to inadequate socialization. (1)
Even among intellectually gifted deaf and hard of hearing people, a longitudinal study found only 43% graduated from a four-year college and 30% were unemployed. (2)
Estimates of the economic burden (in 1990 dollars) of childhood hearing loss (which reportedly have been used in actual settlements) suggest a lifetime loss of income in the $300,000 to $500,000 range, along with significant additional special living and medical expenses. (3)

Transition Into Adulthood
A CDC study that followed school-aged children identified with hearing loss into young adulthood (21 through 25 years of age) found that: About 40% of young adults with hearing loss identified during childhood reported experiencing at least one limitation in daily functioning. (1)
About 70% of young adults with hearing loss without other related conditions (such as intellectual disability, cerebral palsy, epilepsy, or vision loss) were employed. (2)
Young adults with hearing loss without other related conditions (such as intellectual disability, cerebral palsy, vision loss, and epilepsy) were less likely than young adults with other related conditions to take part in risky behaviors (such as smoking and abusing alcohol). (3)

During the 1999 - 2000 school year, the total cost in the United States for special education programs for children who were deaf or hard of hearing was $652 million, or $11,006 per child. (1)
The lifetime educational cost (year 2007 value) of hearing loss (more than 40 dB permanent loss without other disabilities) has been estimated at $115,600 per child. (2)
It is expected that the lifetime costs for all people with hearing loss who were born in 2000 will total $2.1 billion (in 2003 dollars). (3)
Direct medical costs, such as doctor visits, prescription drugs, and inpatient hospital stays, will make up 6% of these costs.
Direct non-medical expenses, such as home modifications and special education, will make up 30% of these costs.
Indirect costs, which include the value of lost wages when a person cannot work or is limited in the amount or type of work he or she can do, will make up 63% of the costs.
Note: These estimates do not include other expenses, such as hospital outpatient visits, sign language interpreters, and family out-of-pocket expenses. The actual economic costs of hearing loss, therefore, will be even higher than what is reported here.

Deaf and The Church
Out of the approximately 6 million Deaf people in North America, only 2 to 4 percent are Christians. (1)
Less than 2% of the Deaf around the world have an active relationship with Jesus.(2)
The Deaf Community is the 3rd (sometimes considered 4th) largest unreached people group with the Gospel of Christ. (3)
Less than 300 individuals are serving in full time deaf ministry worldwide.
