Encyclopedia > Designated Market Area

A designated market area is a group of counties in the United States that are covered by a specific television station. The term was coined by A.C. Nielsen Media Research. There are 210 DMAs in the United States.

The size of a DMA is determined by the number of television households contained within that area, and the percentage the area's population in relation to the total population of the United States. These figures are then used by Nielsen to determine ratings for specific television shows and television stations.
