(CNN) - While more Americans continue to identify as conservatives rather than liberals, new numbers by Gallup indicate that the percentage who label themselves themselves as liberals is at a new high.
Twenty-three percent of Americans identified themselves as liberals last year, up a percentage point from 2012 and four points over the past decade, and its the highest level since Gallup started regularly measuring ideology in the current format in 1992.
But that's still far below the 38% who identified themselves as conservatives in 2013, which was down a point from the previous year. Thirty-four percent labeled themselves as moderates, also down a point from 2012.
"The rise in liberal identification has been accompanied by a decline in moderate identification," says a release by Gallup.
Gallup says their 2013 results are based on more than 18,000 interviews from 13 separate polls they conducted last year.
