Ethnic history
The earliest known inhabitants of the Saint Paul area, from about 400 AD, were members of the Hopewell tradition, who buried their dead in mounds on the river bluffs (now Indian Mounds Park). The next known inhabitants were the Mdewakanton Dakota in the 17th century, who fled their ancestral home of Mille Lacs Lake in central Minnesota in response to westward expansion of the Ojibwe nation. The Ojibwe later occupied the north (east) bank of the Mississippi River.
By 1800, French-Canadian explorers came through the region and attracted fur traders. Fort Snelling and Pig's Eye Tavern also brought the first Yankees from New England and English, Irish, and Scottish immigrants, who had enlisted in the army and settled nearby after discharge. These early settlers and entrepreneurs built houses on the heights north of the river. The first wave of immigration came with the Irish, who settled at Connemara Patch along the Mississippi, named for their home, Connemara, Ireland. The Irish became prolific in politics, city governance, and public safety, much to the chagrin of the Germans and French, who had grown into the majority. In 1850, the first of many groups of Swedish immigrants passed through Saint Paul on their way to farming communities in northern and western regions of the territory. A large group settled in Swede Hollow, which later became home to Poles, Italians, and Mexicans. The last Swedish presence moved up St. Paul's East Side along Payne Avenue in the 1950s.
Of people who specified European ancestry in the 2005–07 American Community Survey of St. Paul, 26.4% were German, 13.8% Irish, 8.4% Norwegian, 7.0% Swedish, and 6.2% English. There is also a visible community of people of Sub-Saharan African ancestry, representing 4.2% of the population.
By the 1980s, the Thomas-Dale area, once an Austro-Hungarian enclave known as Frogtown (German: Froschburg), became home to Vietnamese and other Southeast Asian people who had left their war-torn countries. A settlement program for the Hmong diaspora came soon after, and by 2000, St. Paul had the largest urban Hmong contingent in the nation. Hmong Americans make up 11% of Saint Paul's population as of 2021. Saint Paul, as well as the Twin Cities area in general, is considered the center of Hmong culture in the U.S. Hmongs are most concentrated in the neighborhoods of Frogtown, Payne-Phalen, Dayton's Bluff, the North End, and the Greater East Side, which are considered ethnic enclaves for Hmong Minnesotans, with a large number of businesses, organizations, and events catering to the Hmong population, such as the Hmongtown Marketplace in Frogtown.
Other large Southeast Asian populations live in Saint Paul, particularly Burmese Americans of the Karen and Karenni ethnic group, who immigrated to the U.S. as refugees in the 2000s and 2010s due to internal conflict and discrimination in Myanmar. Minnesota is believed to have the largest population of Karen Americans, with a population of 12,000 in 2017, who are mostly concentrated in Saint Paul. Burmese and Karen residents of Saint Paul make up 5.2% of the population in 2021, and are most concentrated in the neighborhoods of the North End, Payne-Phalen, and Frogtown.
Mexican immigrants have settled in Saint Paul since the 1930s; although Mexican populations exist throughout Saint Paul, by far the largest concentration of Mexican Americans is on Saint Paul's West Side, where Mexicans form a plurality of the population; Mexico opened a foreign consulate there in 2005. Saint Paul also has a large population of Central Americans, particularly Salvadorans, throughout eastern St. Paul and the West Side.
St. Paul has become home to a large number of Somalis and Ethiopians since the 1990s, largely as refugees fleeing conflict in their home regions. Somali and Ethiopian populations are largest in the neighborhoods of Summit-University and Frogtown, where there are many businesses and organizations for Somali and Ethiopian populations.
African Americans in Saint Paul initially entered through servitude to officers at Fort Snelling, marking a crucial point in their history. Despite the absence of legal slavery in Minnesota, Army officers were permitted to bring their enslaved individuals into the region. Today, African Americans are one of the largest groups among Saint Paul's population; African Americans make up approximately 14% of Saint Paul's population, the second-largest background group, before Hmongs and after German Americans. The city's African American residents are concentrated in its central and eastern neighborhoods.
Most Saint Paul residents claiming religious affiliation are Christian, split between the Roman Catholic Church and various Protestant denominations. The Roman Catholic presence comes from Irish, German, Scottish, and French Canadian settlers, later bolstered by Hispanic immigrants. There are Jewish synagogues such as Mount Zion Temple and significant populations of Hindus, Muslims, and Buddhists. Among neopagans in Minnesota, the city has been dubbed "paganistan" due to its large Wiccan population.
