Pew:

Some 15% of adults now qualify as “cord cutters” – meaning they once had either cable or satellite TV but no longer do. Another 9% never had either cable or satellite service.

Young adults are the most likely cord cutters; 19% of adults between the ages of 18 and 29 have severed the ties that they once had with cable or satellite service. Another 16% of young adults say they have never had pay TV in the first place.
