Dickinson County is part of the Iron Mountain, MI–WI micropolitan statistical area.

According to the U.S. Census Bureau, the county has a total area of 777 square miles (2,010 km²), of which 761 square miles (1,970 km²) is land and 16 square miles (41 km²) (2.0%) is water.^[5] Along with its western neighbor Iron County, it is one of only two landlocked counties in the Upper Peninsula.

In 2020, the county had a population of 25,947.^[3]

The 2010 American Community Survey 3-year estimate indicated the median income for a household in the county was $42,331 and the median income for a family was $52,222.^[14] Males had a median income of $31,402 versus $14,957 for females. The per capita income for the county was $22,583. About 3.4% of families and 10.9% of the population were below the poverty line, including 11.4% of those under the age 18 and 11.3% of those age 65 or over.

The county government operates the jail, maintains rural roads, operates the major local courts, keeps files of deeds and mortgages, maintains vital records, administers public health regulations, and participates with the state in the provision of welfare and other social services. The county board of commissioners controls the budget but has only limited authority to make laws or ordinances. In Michigan, most local government functions — police and fire, building and zoning, tax assessment, street maintenance, etc. — are the responsibility of individual cities and townships. In the 2006 elections, it was also the most supportive county of proposal 2, a state constitutional amendment banning affirmative action programs. It received 74.2% support in the county.

The county was a bellwether in every presidential election from 1920 to 2004 (with exception to 1968).
