Olmsted County, Minnesota

Olmsted County is a county located in the southeastern part of the U.S. state of Minnesota. As of the 2020 United States Census, its population was 162,847, making it the seventh-most populous county in the state. The county seat is Rochester, Minnesota, a major international center for healthcare and the home of the world-renowned Mayo Clinic.

History

The region that became Olmsted County was originally inhabited by the Dakota people and later the Ojibwe. The county was created by the Minnesota Territorial Legislature in 1855 and officially organized in 1858, the year Minnesota achieved statehood. It was named for David Olmsted, the first mayor of St. Paul and a member of the territorial council. Early settlement was driven by agriculture, but the county's trajectory changed dramatically with the arrival of William Worrall Mayo and the subsequent founding of the Mayo Clinic after the 1883 Rochester tornado. Historic sites like the Plummer Building and the Chateau Theatre reflect this growth. The county also played a role in the Dakota War of 1862, with settlers seeking refuge at Fort Snelling.

Geography

According to the United States Census Bureau, the county has a total area of 655 square miles, of which 653 square miles is land and 2.2 square miles is water. The primary waterways are the Zumbro River and the Root River, which flow through the Driftless Area, a region bypassed by the last continental glacier. Significant natural features include Chester Woods Park and Oxbow Park and Zollman Zoo. The county's terrain consists of rolling hills, river valleys, and farmland, and it is bordered by Wabasha County to the north, Winona County to the east, Fillmore County to the south, and Dodge County and Goodhue County to the west.

The racial makeup was 78.8% White, 9.1% Asian, 6.1% Black or African American, and 4.1% identifying as Hispanic or Latino. The county has a significant foreign-born population, largely due to the international draw of the Mayo Clinic and IBM. Educational attainment is high, with over 45% of adults holding a bachelor's degree or higher. The largest ancestry groups reported are German, Norwegian, Irish, and English.

The county is also a hub for biotechnology and life sciences research, supported by entities like the Mayo Clinic College of Medicine and Science and the University of Minnesota Rochester. While agriculture remains present, it is a smaller component of the overall economy compared to other Minnesota counties. The Rochester International Airport facilitates business and medical travel.
