What percent of people in the world speak Korean?

It's difficult to give an exact percentage of people who speak Korean in the world. This is because:

* Defining "speak" is tricky: Does it mean native speakers, fluent speakers, or simply people who understand some Korean?

* Reliable global language data is limited: There's no single, universally accepted source for this information.

However, we can provide some estimates:

* Native speakers: There are approximately 77 million native Korean speakers in the world, mainly concentrated in South Korea and North Korea. This number accounts for about 1% of the global population.

* Total speakers (including non-native): This number is much harder to determine. Estimates suggest there could be around 80 million Korean speakers worldwide, including those who learned Korean as a second language.

Therefore, a rough estimate would be that around 1% of the world's population speaks Korean as their native language, and possibly a slightly higher percentage if we consider non-native speakers.
