approx 1 in 1 or 70.00% or 190.4 million people in USA [Source statistic for calcuation: "70-80% of cases of congenital hearing loss are not associated with any syndrome in the US, Genetics Home Reference website" -- see also general information about data sources]
About prevalence and incidence statistics:
The term 'prevalence' of Nonsyndromic deafness usually refers to the estimated population
of people who are managing Nonsyndromic deafness at any given time.
The term 'incidence' of Nonsyndromic deafness refers to the annual diagnosis rate,
or the number of new cases of Nonsyndromic deafness diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
