What is a Designated Market Area (DMA)?
A Designated Market Area (DMA) is a Nielsen media-market geography used to group U.S. counties into TV / advertising markets. Each market has a three-digit DMA code — for example 641 for SAN ANTONIO.
DMAs are not the same as metro statistical areas, area codes, or ZIP boundaries. A single DMA can span multiple states, and large metros may dominate a market while nearby counties still belong to the same advertising footprint.
