DMA® Regions

DMA® data is essential for any marketer, researcher or organization seeking to use standardized geographic areas within their business.

DMA® (Designated Market Area) regions are the geographic areas in the U.S. in which local television viewing is measured by Nielsen. 

A DMA® region is a group of counties and zip codes that form an exclusive geographic area in which the home market television stations hold a dominance of total hours viewed.

There are 210 DMA® regions, covering the entire continental U.S., Hawaii, and parts of Alaska. DMA® boundaries and data are solely owned and exclusive to Nielsen.
