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.
Details
The Designated Market Areas (DMAs) dataset includes:
- DMA boundary data
- DMA point (inventory) data
- DMA name and 3-digit code
- Total area of each DMA (in square miles)
- 210 distinctive DMAs within U.S. including Hawaii and Alaska
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
