With this in mind, I thought it would be helpful to aggregate as many facts and figures about retirement as possible into one source, so current retirees and pre-retirees have easy access to information that could better their financial situation. April data from the St. Louis Federal Reserve shows that the U.S. personal savings rate is only 5.4%, trailing that of many developed nations. The Consumer Price Index for the Elderly, or CPI-E, shows that as of Dec. 2011, housing expenses equated to 44.5% of total costs for seniors.
