Designated Market Areas
Designated Market Areas (DMAs) delineate the geographic boundaries of 210 distinctive regions to assess TV penetration of audience counts within the U.S. for a viewership year. The DMA code is created by Nielsen’s assignment of a 3-digit number for identification and processing purposes.
Features
- DMA Boundaries are defined by current county boundaries; when viewership within a county is split, or if a DMA boundary splits a county, zip code boundaries are used instead
- Boundaries are updated annually as DMA county assignments change to reflect the most current television year
