President Joe Biden is the least popular modern U.S. president in history at this point in their presidency, according to new polling data.

With an average disapproval rating of 55.8% and an approval rating of 37.7%, according to poll website FiveThirtyEight on Saturday, Biden is more unpopular than any other modern commander-in-chief 1,054 days into their presidency.

His approval rating may be even lower, as a TIPP Insights survey earlier this month showed his approval rating at 33%, an all-time low for Biden at the polling firm. That poll of 1,464 adults was conducted Nov. 29–Dec. 1 and had a 2.6% margin of error.

Meanwhile, more people disapprove of Biden at this point in his presidency than all other modern presidents dating back to Harry S. Truman, per FiveThirtyEight.
