The region consists of eight counties (five in Nebraska and three in Iowa), and extends over a large area on both sides of the Missouri River. Covering 4,407 square miles (11,410 km²) and with a population of 967,604 (2020), ^[1] the Omaha metropolitan area is the most populous in both Nebraska and Iowa (although the Des Moines–West Des Moines MSA is the largest MSA centered entirely in Iowa), and is the 58th most populous MSA in the United States.

The region is locally referred to as "Big O", "the Metro Area", "the Metro", or simply "Omaha". The core counties of Douglas and Sarpy in Nebraska and Pottawattamie in Iowa contain large urbanized areas; the other five counties consist primarily of rural communities. The larger Omaha–Fremont, NE–IA, Combined Statistical Area (CSA) encompasses the Omaha MSA as well as the separate Fremont, NE, Micropolitan Statistical Area, which consists of the entirety of Dodge County, Nebraska.

Standard definitions for United States metropolitan areas were created in 1949; the first census which had metropolitan area data was the 1950 census. At that time, the Omaha–Council Bluffs metropolitan area comprised three counties: Douglas and Sarpy in Nebraska, and Pottawattamie in Iowa. No additional counties were added to the metropolitan area until 1983, when Washington County of Nebraska was added. Cass County, Nebraska, was added in 1993; Saunders County in Nebraska and Harrison and Mills counties in Iowa became part of the Omaha–Council Bluffs metropolitan area in 2003.
