* Closed Country: North Korea is a very closed country, and official data on language demographics is not readily available.
* Limited Information: Information that does come out is often unreliable or subject to political biases.
* Official Language: The official language of North Korea is Korean.
* Minority Languages: While Korean is the dominant language, there are likely to be smaller communities speaking other languages, such as Chinese, Japanese, or Russian, due to historical ties and trade.
* Dialects: Within Korea itself, there are different dialects, with North Korean dialects often being distinct from those spoken in South Korea.
Therefore, any attempt to provide specific percentages would be highly speculative.
However, we can say with certainty that Korean is the overwhelmingly dominant language in North Korea, with any other languages spoken by comparatively small communities.
