E. CONCLUSION
Under current law, the cost of Social Security will generally increase faster
than the program’s income because of the aging of the baby-boom generation,
continuing low fertility compared to the baby-boom period, and
increasing life expectancy. Based on the Trustees’ best estimate, program
cost will exceed non-interest income in 2011, as it did in 2010, and remain
higher throughout the remainder of the 75-year projection period. Social
Security’s combined trust funds are projected to increase with the help of
interest income through 2022 and allow full payment of scheduled benefits
on a timely basis until the
trust funds become exhausted in 2036. At that
time, annual non-interest income to the trust funds is projected to equal about
77 percent of program cost. By 2085, annual non-interest income is projected
to be about 74 percent as large as the annual cost of the OASDI program.
