31699 Guatemalan Sign Language 10000-99999 73,000-640,000 "A recent government-sponsored survey estimated a deaf population of 73,000 (Edith Paz 2006, personal communication), but other estimates reach up to 640,000.... Forty percent of all Guatemalans with a significant degree of hearing loss are believed to use a sign language, according to a source who previously worked with the national disability organization, CONADI. When applied to the figures above, this indicates that between 28,000 and 256,000 Guatemalans use sign language and have a deaf ethnolinguistic identity."
