Final answer:
Korean immigrants' high church involvement is attributed to maintaining cultural practices within ethnic communities, the Christian-dominant social environment in the U.S., and historical religious affiliations in Korea.
Step-by-step explanation:
High levels of church involvement among Korean immigrants were the result of a synthesis of several factors, including cultural heritage, community formation in a new environment, and the diffusion of religion. During times of urbanization, immigrants often formed ethnic neighborhoods, such as "little Korea", where they could maintain their cultural practices, including their religious beliefs. Moreover, the United States, influenced by its Christian majority, presented a social landscape where Christianity was prevalent, encouraging immigrants to join Christian churches not only for spiritual reasons but also as a means of social support and community building.
Korean immigrants' religious association was further compounded by historical influences back in their homeland, where Christianity had become a significant part of South Korean culture. Following the establishment of a Communist government in North Korea, many Christians fled to South Korea and subsequently, a significant number immigrated to the U.S. seeking freedom and better economic opportunities, carrying their Christian faith with them. Therefore, community support, social integration, and historical religious ties all contributed to the high levels of church involvement among Korean immigrants.
