WASHINGTON, D.C. -- The way Americans identify themselves ideologically was unchanged in 2021, continuing the close division that has persisted in recent years between those describing themselves as either conservative or moderate, while a smaller share identifies as liberal. On average last year, 37% of Americans described their political views as moderate, 36% as conservative and 25% as liberal.

Gallup's political ideology trend, dating from 1992, is based on annual averages of its multiday national telephone surveys conducted throughout each year. The 2021 results encompass interviews with more than 12,000 U.S. adults. Unlike party ID, which varied considerably from one quarter to the next in 2021, Americans' description of their political views on the conservative-to-liberal spectrum showed no meaningful movement throughout the year.

Long term, Americans' political ideology hasn't varied greatly, but moderates were generally the lead group by a slight margin in most years from 1992 to 1998. Between 1999 and 2008, moderates and conservatives were about evenly matched (within two percentage points of each other) -- similar to the pattern from 2015 through today. By contrast, in a unique period from 2009 to 2014 -- the first six years of Barack Obama's presidency -- conservatives held a slight edge.
