Religion , the oldest church in
Iowa Dubuque has always had a strong religious tradition. Local
Catholic settlers established
St. Raphael's Cathedral in 1833. The city also played a key role in the expansion of the Catholic Church into the Western United States, as it was the administrative center for Catholics in
Iowa,
Minnesota,
North Dakota, and
South Dakota. Many important Catholic religious leaders have lived in Dubuque, including its first bishop
Mathias Loras, Fr.
Samuel Mazzuchelli,
Clement Smyth, and Mother
Mary Frances Clarke, BVM. Catholic parishes around the city include Saint Raphael's,
Saint Mary's,
Sacred Heart,
Holy Ghost,
Saint Patrick's,
Saint Joseph the Worker, Resurrection, Saint Columbkille's, and Saint Anthony's. In 2010, Catholic adherents who regularly attended services made up about 53-percent of Dubuque County residents. This contrasts with Iowa as a whole, which was about 17% Catholic in 2010. Five religious colleges, four area
convents, and a nearby
abbey and
monastery add to the city's religious importance. The city proper is home to 52 different churches: 11 Catholic, 40
Protestant, an
Eastern Orthodox, a Jewish synagogue, and a mosque. Most of non-Catholic population in the city belongs to various Protestant denominations. Dubuque is home to three theological seminaries:
St. Pius X Seminary, a college seminary for Catholic men discerning a call to ordained priesthood; the
University of Dubuque Theological Seminary, with the
Presbyterian Church USA; and the
Wartburg Theological Seminary with the
Evangelical Lutheran Church in America. The University of Dubuque and Wartburg train both lay and ordained ministers for placements in churches nationwide. Ben Jacobs of
The New Republic described Dubuque as "one of the most Catholic areas in" the United States.
Ethnic groups Several
Marshallese immigrants coming to attend a seminary program in the city in the 1970s were the start of the city's Marshallese population. Circa 2024, the number of ethnic Marshallese in the Dubuque area numbered about 1,400. ==Economy==
