Constituent Matching - DMA and MSA

Certain media organizations are associated with a Designated Market Area (DMA) or a Metropolitan Statistical Area (MSA) to identify them by local area. Luminate Online's media database includes this data as well as the ZIP codes that map to those areas. Using this mapping data, Luminate Online can match an advocate's 5-digit ZIP code to his or her local media by mapping the ZIP code to a DMA or an MSA. When Constituent Matching is enabled, advocates taking action on the LTE alert will be matched to their local media organizations.

National Newspapers (such as USA Today) and Online Media do not have ZIP code matching; anyone is eligible to participate in the alert. Daily Newspapers normally use the MSA. If the data does not include the MSA, the DMA is used instead.

Area Description Used for Matching with Media Type

A Designated Market Area is a group of counties in the United States that is covered by a specific group of television stations. The term was coined and trademarked by Nielsen Media Research.

There are 210 DMAs in the United States. These market areas are also used to define restrictions on rebroadcasting of broadcast television signals.

  • Television Stations

  • Daily Newspapers (if MSA is unavailable)


Metropolitan Statistical Area, as defined by the Office of Management and Budget, is used to designate a United States metropolitan area.
