In Mexico, approximately 2.3 million people have a hearing disability. According to the World Health Organization, by 2050, one in four people in the world, almost 2.5 billion, will have hearing loss due to lack of healthcare access. Since June 10, 2005, Mexican people have celebrated the National Day of Mexican Sign Language (LSM, its Spanish acronym) to promote and create an inclusive, equitable environment for people with this disability.
