This article examines how retirement income is likely to change for boomers and persons born in generation X compared with current retirees. We use the MINT model to project retirement income, poverty rates, and replacement rates for current and future retirees at age 67. We find that retirement incomes will increase over time, and poverty rates will fall. Projected income gains are larger for higher than for lower socioeconomic groups, leading to increased income inequality among future retirees. Boomers and GenXers are less likely to have enough postretirement income to maintain their preretirement standard of living compared with current retirees.
