Income security when health impairment or other social risks occur is a major objective of welfare states. This comparative study uses register data from four Nordic welfare states for examining equivalized disposable income during the last 12 years alive among men and women who died when aged 55–69 years old. The analysed outcome indicates the aggregate result of a varied set of income maintenance mechanisms. Median income increased in the Finnish, Norwegian and Swedish samples, but decreased somewhat in Denmark, probably due to relatively frequent transitions to retirement and larger income drops after retirement than in the other Nordic countries. Analyses of comparison samples weighted by propensity scores indicated a better income development among those who lived beyond the observation period than among those who died. The higher educated had a more favourable income development during the years prior to death than those with low education.
