The National Retirement Risk Index (NRRI) measures the share of working-age American households at risk of being unable to maintain their standard of living in retirement. The Index results from comparing households' projected replacement rates—retirement income as a percent of pre-retirement income—with target rates that would allow them to maintain their living standard. The NRRI is produced by The Center for Retirement Research at Boston College (CRR) and is exclusively sponsored by Prudential.
The last update to the NRRI, published in October 2012 and based on 2010 data, indicated that 53% of households are at risk. In new research, the CRR finds that, despite rebounds in the stock and housing markets, Americans' retirement prospects improved only modestly, with 50% of households still at risk.
A Prudential summary of this research, "Planning for Retirement: The Impact of Market Recoveries on Retirement Readiness", examines three important ways to improve Americans' retirement prospects.
