While the Korean population in the U.S. is primarily concentrated in major metropolitan areas like Los Angeles, New York, Chicago, and Washington D.C., St. Louis also has several advantages for Koreans looking to settle down. The relatively low cost of living, excellent healthcare infrastructure, stable job market, and a moderately sized Korean community are key reasons why many choose St. Louis as their home. In particular, Korean professionals working in healthcare, engineering, and research often select St. Louis as their place of residence.

In terms of cost of living, St. Louis is significantly cheaper compared to other major U.S. cities. The cost of purchasing a home or renting is often less than half that of Los Angeles or New York, and grocery and utility costs are well below the national average. For example, in the suburbs of St. Louis, it is possible to buy a single-family home with 3 to 4 bedrooms for a budget of $300,000 to $400,000. Missouri also has a relatively low income tax rate compared to other states, which can make the effective income feel higher. However, it is important to note that some cities in Missouri impose an additional local earnings tax, so it's necessary to check this when choosing a place to live.

St. Louis is also one of the cities in the U.S. with a high level of healthcare. Washington University School of Medicine and Barnes-Jewish Hospital provide world-class medical services, and St. Louis Children's Hospital is recognized as one of the top pediatric hospitals in the country. With many medical education institutions such as medical, dental, and pharmacy schools, there is a significant number of Korean international students and residents in St. Louis. This healthcare infrastructure is a major reassurance for Korean families.

In terms of education, St. Louis is competitive as well. Washington University in St. Louis is a prestigious private university ranked within the top 20 nationwide, known for its academic excellence and research output. Saint Louis University, a traditional Jesuit institution, excels in fields such as medicine, law, and business. The quality of public schools varies by area, so Korean families tend to prefer suburban regions with good school districts, such as Clayton, Ladue, and Chesterfield, which are known for their high-ranking educational systems in Missouri.

From the perspective of the Korean community, St. Louis has a small but strong network. The Korean American Association of St. Louis, along with Korean churches, Korean schools, and the Korean Chamber of Commerce, are active in the area. There are Korean schools that provide Korean language education, creating an environment for children to learn about Korean language and culture. The presence of Korean grocery stores like H Mart has also made it easier to obtain ingredients necessary for Korean cooking, contributing to the improvement of the living environment for Koreans. Overall, St. Louis is an attractive city for Korean families and professionals seeking a quiet and stable lifestyle.
