Estimates of the number of speakers of Lensegua and/or Guatemalan Sign Language vary widely, although there is wide agreement that the occurrence of congenital deafness, prelingual deafness, and adult-onset deafness are significantly higher than what the World Health Organization estimates for the global population, due to poverty, lack of access to medicine, distance from hospitals, not to mention potential environmental or genetic reasons.
The number of Lensegua and/or Guatemalan Sign Language speakers is uncertain but generally accepted to be higher than WHO estimates for the global population. This can be attributed to congenital deafness, prelingual deafness, adult-onset deafness, poverty, lack of medical resources, distance from healthcare facilities, and possibly environmental or genetic factors.
