Last week the Congressional Budget Office (CBO) released a new report with updated long-term projections for Social Security. This report is a follow up to the last projections for Social Security released by CBO back in December, 2007. CBO Director Peter Orszag blogged last week on improvements made in this updated report: The projections released today 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. For example, these projections assume that future immigrants will be younger and more numerous than was assumed in 2007. (This change was included in the 2008 Social Security trustees' report; CBO adopts the trustees' aggregate demographic assumptions.) As a result of this and other changes, CBO projects somewhat smaller future deficits than we did in our 2007 projections. This report, while not focused on this issue, continues to show the crux of our long-term fiscal problem lies elsewhere - namely in rapidly rising health care services delivered through an inefficient system.
