(CNN) In Gallup's 2018 poll, released Monday, a declining number say they are proud to be an American, with less than three-quarters saying they are, down six points since 2016.

The driving force behind this lack of pride is a dip among Democrats, with their number dropping from 45% in 2016 to 32% now who said they are "extremely proud." Republicans moved up six points in the past two years, and independents inched down by three points.

Gallup has been tracking patriotism for a while, starting in 2001 when 87% said they were proud to be an American.

Other polls have recorded a similar movement, with an MTV/AP-NORC poll in May 2018 finding that young people (ages 15-26) are much more likely to say that "patriotic" describes their parents generation better than it describes their generation. When the parents were asked, they also believed their own generation to be more patriotic than their children's.

PRRI poll released in June 2013 found similar numbers to Gallup in 2013 when asking about pride in being an American, with half saying they're "extremely proud" and 31% saying they're "very proud." Four percent said they were "only a little proud" or "not at all proud."
