[Excerpt] The Congressional Budget Office (CBO) regularly prepares long-term projections of the future paths of revenues and outlays for the Social Security program. This latest report presents projections for the 75-year period from 2008 through 2082. (All years referred to in this report are calendar years.) The projections differ somewhat from earlier results because of newly available programmatic and economic data, updated assumptions about future demographic and economic trends, and improvements in CBO’s models. Such long-term projections are necessarily uncertain; nevertheless, the general conclusions presented here hold true under a wide range of assumptions.
