Gallup will no longer track presidential approval ratings after more than eight decades doing so, the public opinion polling agency confirmed to The Hill on Wednesday.

The company said starting this year it would stop publishing approval and favorability ratings of individual political figures, saying in a statement it “reflects an evolution in how Gallup focuses its public research and thought leadership.”

The Gallup Presidential Approval Rating has for decades been the among the top barometers cited by media outlets measuring public opinion of the president’s performance.

President Trump has seen his rating by the agency slip in recent months, peaking at 47 percent last February and dipping to less than 37 percent in its last poll taken in December.
