Denmark’s retirement age is now the highest in the world at age 70. What changes might be coming for the US? If we look at Social Security claiming ages, the “retirement age” has also changed since Social Security enacted reforms back in 1983. Looking to address funding concerns, age 67 became the starting point to claim full benefits in 2025, impacting millions of Americans born in 1960. With people living longer and entitlements like Medicare hard to touch, that number might continue to rise in the near future.
