We employ German social security records and a comprehensive microsimulation model to investigate intra-generational lifetime
income inequality and redistribution at the level of birth-year cohorts, starting with those born in 1935. We detect a striking
secular rise of lifetime income inequality, both pre-fisc and post-fisc. On entire life-cycles, the German tax-transfer system
is found to be progressive and generating substantial effects on the disposable incomes of the two extreme deciles of the
lifetime income distribution. Governmental lifetime income redistribution displays an inverted-U shape over cohorts and is
significantly smaller than on an annual basis. Differential mortality increases lifetime income inequality by about 5 percent.
We develop a money-metric welfare measure that takes the value of greater longevity into account. We find that differential
mortality increases lifetime welfare inequality by about 13 percent.
