The same survey finds roughly two-thirds of Americans, 64%, reporting that they typically drink at least one cup of coffee per day. Perhaps surprisingly, given the explosion of upscale coffee houses and specialty coffee products being marketed to consumers over the past decade, this is nearly identical to the 63% who drank coffee in 1999.

Additionally the number of coffee cups consumed by regular coffee drinkers has not increased, and may have even declined, with the average number of reported cups consumed by coffee drinkers registering 2.5 today, compared with 2.9 in 1999. Among all Americans, including those who drink no coffee, daily coffee consumption averages 1.6 cups today compared with 1.8 cups in 1999.
