Improved
Meta Ads: Comscore Market reporting dimension
July 23rd, 2026
Meta has fully discontinued Nielsen DMA (Designated Market Area) data as of June 22, 2026, replacing it with Comscore Market as its new geographic taxonomy, stating it "a more sustainable and scalable" solution for long-term measurement.
As a result:
- The DMA breakout dimension has been deprecated and no longer returns data, in line with Meta's own change.
- Comscore Market is now available as a breakout dimension for Meta Ads reports, giving you the geographic view Meta now provides.
If you have existing reports, filters, or templates built on DMA, please update them to use Comscore Market.
