When a deaf child is born to a hearing family, they will often develop a miming system in the home to reach a level of understanding one another. This results in what some people refer to as "home sign language". When a large population of a community is born deaf they may converge to produce their own communication system on a semi-larger scale, resulting in what is known as a "village sign language". In fact, there are both intentionally and non-intentionally cultivated sign languages, but all sign languages start with a desire for human connection.
Micro Sign Language Communities:
Some sign languages appear to be spontaneous, only occurring due to a high rate of incidental intergenerational deafness in communities or through prolonged contact of deaf community members in schools without existing sign language implementation.
Macro Sign Language Communities:
Some sign languages are spread from pre-existing structures that share them with another institution. This can be through natural migration, but is more often than not related to political structures.
