Jimmy Carter can add another title to a lifetime of achievements: He's now the longest-living U.S. president.
As of Thursday evening, the 39th commander-in-chief is 94 years and 172 days old — surpassing George H.W. Bush, who died in November at 94 years and 171 days old.
"We at The Carter Center are grateful for his long life of service that has benefitted millions of the world's poorest people," Deanna Congileo, a spokeswoman for the Carter Center, told NBC News.

Carter, the first American president born in a hospital, turned 94 in October. He was Georgia's 76th governor before winning the presidency in 1976 as a Democrat.
As president, he oversaw the Panama Canal treaties as well as the passage of educational programs and environmental protection legislation, such as the Alaska Lands Conservation Act.
Carter's work on the Camp David Peace Accords, where he mediated a peace agreement between Egypt and Israel beginning in 1978, became one of his major foreign policy undertakings.
He also faced some major setbacks in foreign policy, one being the conflict in Iran after the fall of the Shah that led to the Iranian Revolution in 1979. The following year, Carter lost the presidential election to former actor and California Gov. Ronald Reagan.
He became a distinguished professor at Emory University in Atlanta in 1982. He and wife Rosalynn opened The Carter Center, a nonprofit, nonpartisan center focused on national and international issues of public policy.
