When Social Security was established in the 1930s age 65 was established as the full-retirement age for people to start collecting benefits. Back then it was no given that a person would reach 65 in order to collect benefits, but today the life expectancy of Americans is well past 65, but the full-retirement age has only increased to 67 for everyone born 1960 and later. As Congress examines how the retirement age should be considered in the future, here is a look at the history of life expectancy as documented by the Social Security’s historian’s office.
Life Expectancy for Social Security
If we look at life expectancy statistics from the 1930s we might come to the conclusion that the Social Security program was designed in such a way that people would work for many years paying in taxes, but would not live long enough to collect benefits. Life expectancy at birth in 1930 was indeed only 58 for men and 62 for women, and the retirement age was 65. But life expectancy at birth in the early decades of the 20th century was low due mainly to high infant mortality, and someone who died as a child would never have worked and paid into Social Security. A more appropriate measure is probably life expectancy after attainment of adulthood.
The majority of Americans who made it to adulthood could expect to live to 65, and those who did live to 65 could look forward to collecting benefits for many years into the future. So we can observe that for men, for example, almost 54 percent of the them could expect to live to age 65 if they survived to age 21, and men who attained age 65 could expect to collect Social Security benefits for almost 13 years (and the numbers are even higher for women).
Also, it should be noted that there were already 7.8 million Americans age 65 or older in 1935), so there was a large and growing population of people who could receive Social Security. Indeed, the actuarial estimates used by the Committee on Economic Security (CES) in designing the Social Security program projected that there would be 8.3 million Americans age 65 or older by 1940 (when monthly benefits started). So Social Security was not designed in such a way that few people would collect the benefits.
The average life expectancy at age 65 (i.e., the number of years a person could be expected to receive unreduced Social Security retirement benefits) has increased a modest 5 years (on average) since 1940. So, for example, men attaining 65 in 1990 can expect to live for 15.3 years compared to 12.7 years for men attaining 65 back in 1940.
