Metropolitan and Micropolitan Areas - Technical Notes
The Office of Management and Budget (OMB) maintains and updates statistical area classifications, a task it has performed every decade since the 1950 Census. As a result of the 2000 Census, the OMB finalized and released new statistical area definitions on February 18, 2004. The area definitions are based on population and commuting within communities.
In South Dakota, there are two basic area types: metropolitan areas and micropolitan areas.
The official definition of a Metropolitan Statistical Area (MSA) is that it must have at least one urbanized area of 50,000 or more population, plus adjacent territory with a high degree of social and economic integration with the core as measured by commuting ties.
South Dakota has two MSAs. In addition, one county in South Dakota (Union) is part of the Sioux City MSA. Below is a table listing the South Dakota counties in MSAs.

|Sioux Falls MSA||Lincoln, Minnehaha, McCook, Turner|
|Sioux City MSA (IA-NE-SD)||Union, SD; Dixon-Dakota, NE; Woodbury, IA|
The Office of Management and Budget also defines a set of areas called micropolitan statistical areas. The official definition of a micropolitan area is at least one urban cluster of at least 10,000 but less than 50,000 population, plus adjacent territory with a high degree of social and economic integration with the core as measured by commuting ties.
According to these definitions for micropolitan areas, South Dakota has nine areas. The table below lists the micropolitan statistical areas and the counties in each area.
