There is an NTID center that gathers information on this topic, Collaboratory on Economic, Demographic, and Policy Studies. According to the 2011 American Community Survey (ACS), about 3.6% of the U.S. population, or about 11 million individuals, consider themselves deaf or have serious difficulty hearing. Of the approximately 1,155,000 people in the Rochester area, 40,000 are Deaf or hard-of-hearing. The Census Bureau is a good resource for limited statistics on DHH persons. If you enter the word hearing in the topic box, and Monroe County, NY in the state, county, or place box, you will get some tables about hearing status in Monroe County, NY. Another good resource is the 2020 Annual Disability Statistics Compendium.
