The Korean Peninsula was first populated by peoples of a Tungusic branch of the Ural-Altaic language family who migrated from the northwestern regions of Asia. Some of these peoples also populated parts of northeast China (Manchuria); Koreans and Manchurians still show physical similarities.

Koreans are racially and linguistically homogeneous. Although there are no indigenous minorities in North Korea, there is a small Chinese community (about 50,000) and some 1,800 Japanese wives who accompanied the roughly 93,000 Koreans returning to the North from Japan during 1959-62.

Korean is a Ural-Altaic language and is related to Japanese and remotely related to Hungarian, Finnish, Estonian, and Mongolian. Although dialects exist, the Korean spoken throughout the peninsula is mutually comprehensible. In North Korea, the Korean alphabet (hangul) is used exclusively, unlike in South Korea, where a combination of hangul and Chinese characters is used as the written language.

Korea's traditional religions are Buddhism and Shamanism. Christian missionaries arrived as early as the 16th century, but it was not until the 19th century that they founded schools, hospitals, and other modern institutions throughout Korea. Major centers of 19th-century missionary activity included Seoul and Pyongyang, and there was a relatively large Christian population in the north before 1945. Although religious groups exist in North Korea, most available evidence suggests that the government severely restricts religious activity.
