Area Overview
Defining the Region
The Sioux City metropolitan statistical area (MSA) is a specific designation established by the United States Census Bureau. It encompasses four counties spread across three states: Iowa, Nebraska, and South Dakota. The core of this region is anchored by the principal city, Sioux City, Iowa. As of the 2020 census, the MSA's population was recorded at 145,940 individuals.[1] It is important to note that Plymouth County, Iowa, was administratively removed from the MSA definition prior to the 2020 census enumeration.[2]
Administrative Structure
The MSA comprises the following counties, reflecting a multi-state regional definition:
- Iowa: Woodbury County
- Nebraska: Dakota County, Dixon County
- South Dakota: Union County
Historically, Plymouth County, Iowa, was also included until its exclusion before the 2020 census.
Temporal Context
The definition and boundaries of Metropolitan Statistical Areas are periodically reviewed and updated by governmental bodies like the Office of Management and Budget. These delineations are crucial for statistical analysis, resource allocation, and understanding regional economic and social linkages. The Sioux City MSA's composition reflects these evolving definitions.

County Governance
Each county operates under its respective state's framework for local governance.
