Korea's population is one of the most ethnically and linguistically homogenous in the world. Except for a small Chinese community (about 20,000), virtually all Koreans share a common cultural and linguistic heritage. With 48.85 million people, South Korea has one of the world's highest population densities. Major population centers are located in the northwest, southeast, and in the plains south of the Seoul-Incheon area.

The Korean language is related to Japanese and Mongolian. Although it differs grammatically from Chinese and does not use tones, a large number of Chinese cognates exist in Korean. Chinese ideograms are believed to have been brought into Korea sometime before the second century BC. The learned class spoke Korean, but read and wrote Chinese. A phonetic writing system ("hangul") was invented in the 15th century by King Sejong to provide a writing system for commoners who could not read classical Chinese. Modern Korean uses hangul almost exclusively with Chinese characters in limited use for word clarification. Approximately 1,300 Chinese characters are used in modern Korean. English is taught as a second language in most primary and secondary schools. Chinese and Japanese are widely taught at secondary schools.
