(GALLUP) PRINCETON, NJ — Forty-two percent of Americans, on average, identified as political independents in 2013, the highest Gallup has measured since it began conducting interviews by telephone 25 years ago. Meanwhile, Republican identification fell to 25%, the lowest over that time span. At 31%, Democratic identification is unchanged from the last four years but down from 36% in 2008.

The results are based on more than 18,000 interviews with Americans from 13 separate Gallup multiple-day polls conducted in 2013.

In each of the last three years, at least 40% of Americans have identified as independents. These are also the only years in Gallup’s records that the percentage of independents has reached that level.
