Koreatown, located in the Mid-Wilshire district of Los Angeles, is the heart and nexus for Koreans in America. In the early 20th century, a small Korean community--many of whom were active leaders and supporters of the Korean independence movement--initially settled around Bunker Hill. The community migrated in the 1930s toward Jefferson Boulevard, near the University of Southern California, to an area known as Old Koreatown. By the late 1960s, following the freeway construction boom and the Hart-Cellar Act of 1965, Korean markets, restaurants, and businesses began to blossom along Olympic Boulevard. Today, Koreatown is a thriving urban center where Koreans, Hispanics, and Bangladeshis coreside in one of the most densely populated and diverse sections of Los Angeles. Its boundaries were officially designated by the Los Angeles City Council on August 20, 2010.
