The Djiboutian community in the United States is small, numbering less than 300 individuals.  Its constituents primarily hail from the Somali and Afar populations, Djibouti's two largest ethnic groups.  Djiboutian nationals of Somali ethnicity are typically aggregated with Somali Americans.
Prior to 1991, when Eritrea obtained its independence, it was a part of Ethiopia. Overall, approximately 20,000 people from Ethiopia moved to the West to achieve higher education and conduct diplomatic missions from 1941 to 1974 under the Emperor Haile Selassie I's rule.  However, the net movement of permanent immigrants remained low during this period as most temporary immigrants ultimately returned to Ethiopia.  The majority of Eritrean immigrants arrived later in the 1990s, following the Eritrean–Ethiopian War.  According to the U.S. Census Bureau, approximately 18,917 people reported Eritrean ancestry in 2000. 
Eritrean Americans have established ethnic enclaves in various places around the country. Most Eritrean immigrants are concentrated in the Washington, D.C., and California areas. The community also has a notable presence in Seattle, Columbus, Minneapolis, Chicago, New York, Atlanta and Dallas. Fairfax Avenue in Los Angeles, California has come to be known as Little Ethiopia, owing to its many Ethiopian and Eritrean businesses and restaurants.
In 1980, the U.S. government passed a bill formally establishing criteria for admitting asylum seekers. Emigration from Ethiopia to the United States subsequently increased, prompted by political unrest during the Ethiopian Civil War. The majority of Ethiopian immigrants arrived later in the 1990s. Immigration to the United States from Ethiopia during this 1992-2002 period averaged around 5,000 individuals per year.  According to the U.S. Census Bureau, 137,012 Ethiopian immigrants lived in the United States as of 2008. 
Founded by Ethiopian publisher Liben Eabisa, Tadias Magazine is today the premier Ethiopian American news source based inside New York.
The first Somalis to arrive in the United States were sailors who came in the 1920s. They were followed by students pursuing higher studies in the 1960s and 1970s, and a few migrants thereafter. However, it was not until the 1990s when the Somali Civil War broke out that the majority of Somalis arrived in the United States. The Somali community in the United States is now among the largest Somali diaspora communities.  According to American Community Survey data, there are approximately 85,700 people with Somali ancestry in the United States as of 2010. 
The city of Minneapolis, Minnesota, now hosts hundreds of Somali-owned and operated businesses offering a variety of products, including leather shoes, jewelry and other fashion items, halal meat, and hawala or money transfer services. Community-based video rental stores likewise carry the latest Somali films and music.
