# List of sign languages by number of native signers

The following are sign languages reported to be used by at least 10,000 people. Additional languages, such as Chinese Sign Language, are likely to have more signers, but no data is available. Estimates for sign language use are very crude, and definitions of what counts as proficiency are varied. For most sign languages, there are no concrete estimates. For instance, it has been reported there are a million signers in Ethiopia, but there are only a fifth that number of deaf people, less than half of whom are fluent in sign, and in addition it is unknown how many different sign languages they use.
According to many highly educated members of the ASL Deaf community, the number of fluent ASL native signers is closer to the tens of millions. Therefore, the statistics listed below, while taken from varying published sources, should be carefully vetted before being disseminated or cited elsewhere.
